  1. I have studied php introduction and php advanced object oriented programming, Was able to get my hands on small projects such as building small websites, Buiding forums. I will like to know which project book is the best php project book guide to guide developers on building dynamic applications(such as social media platforms, educational platform, online libraries...etc) using php. Which is the best with detail and straight forward explanation.
  2. (Using the example in Modern javascript) Am trying to submit data for processing and insertion into the database using php but it could not work and I don't why and these are the steps taking so far. 1. Using php alone, am able to insert data into the database an d this is the php code. <?php try { $linkas = 2; require_once 'db/DBConnect.php'; $errors = []; $good = true; if ($_SERVER['REQUEST_METHOD'] == 'POST' && !empty($_POST['testimony'])): $testimony = filter_input(INPUT_POST, 'testimony', FILTER_SANITIZE_STRING); if (strlen($testimony) < 20): //report error and do
  3. Uncaught TypeError: Cannot set property 'onreadystatechange' of undefined at window.onload (test.js:4). The above error message is what is displayed on the console while trying to run the ajax example on page 433 of the book. What can be done to rectify it? Any clue or answer will be appreciated.
  4. Hi, In script 15.10, login.js, page 487, there's the AJAX request of the server-side script login_ajax_php. The actual request of the script (line 89-92, $.Ajax(options)) comes after all the tests on the response (line 68, if (respnse == 'CORRECT')...). I can't understand how the AJAX request knows that it has to call the server-side script login_ajax_php. To put it in other words: 1) login.php displays the form 2) when you click on the submit button, login.js starts 3) login.js calls login_ajax.php (BUT HOW? WHERE? WHEN?) 4) login_Ajax.php performs the echo 5) login.js re
  5. Hi I'm trying to find out 2 things, 1) how to pass a button value that comes from mysqli while loop to javascript then on to Ajax script. 2) how to pass a php array on to javascript and then onto the Ajax script. I will be really grateful if anyone could help. many thanks sam
  6. I tried to implement the code in Chapter 14 for adding favorites and it's not working. How can I see what the problem is considering it's using an AJAX call?
  7. Hello, I'm using Fullcalendar for Yii2 (https://github.com/philippfrenzel/yii2fullcalendar-demo) and I want to save with Ajax the event when I click on a date. The datas commes from the dropdownlist. It seems that my code couldn't find the function in my controller, maybe it's the Url ? My view with JS and the link to my funstion Ajax on my controller : <?php $form = ActiveForm::begin(); ?> <div class="row"> <div class="col-md-4"> <?= $form->field($feuille_de_jour_responsable, 'ID_Categorie')->dropDownList(CategorieF
  8. Hey! New to these forums, but I just started web dev and about to finish the book. I am having a hard time with one thing. Well, the entire Ajax chapter is hard for me, but one part in particular I don't understand, it is a chunk of code inside the login.js for the section. // Create an object of Ajax options: var options = new Object(); // Establish each setting: options.data = data; options.dataType = 'text'; options.type = 'get'; options.success = function(response) { // Worked: if (response == 'CORRECT') { //
  9. EDIT: In the meantime I solved this - the answer is at the end Hi, First of all - I apologize - my English is bad. I have this JSON data in file mydata.json: [ {"name": "Aster", "product": "aster", "stock": "10", "price": "2.99"}, {"name":"Daffodil","product":"daffodil","stock":"12","price":"1.99"}, {"name":"Rose","product":"rose","stock":"2","price":"4.99"}, {"name":"Peony","product":"peony","stock":"0","price":"1.50"}, {"name":"Primula","product":"primula","stock":"1","price":"3.12"}, {"name":"Snowdrop","product":"snowdrop","stock":"15","price":"0.99"} ] I want to use t
  10. I have an HTML table generated by PHP querying from MySQL table. <table> <tr> <th>Sl</th> <th>ID</th> <th>Article Name</th> <th>Publish Status</th> </tr> <?php $i = 1; foreach ($obj->showAllFromTable('pattern') as $pattern) { extract($pattern); ?> <tr> <td><?php echo $i++; ?></td> <td><?php echo $id; ?></td> <td><?php echo $patte
  11. I have set up code to retrieve data from a MySQL database using AJAX. The data is retrieved in JSON format. (Thank you, Larry, for your clear explanations on how to do all this.) Using firebug, I know that the data is returning properly. Here, for example, is what I see in the firebug console when I use the line console.log(JSON.stringify(response, null, 4)); [ { "0": "1", "1": "Allen", "2": "Wyatt", "3": "allen@sharonparq.com", "4": "8013692885", "5": "8016072035", "6": "8013692885", "7": "238 E. 550 N.", "8": "", "9": "Orem", "10": "UT", "11": "84057", "12": "about", "13": "", "14":
  12. Hi, First of all, my English is very bad, but I hope you will understand me. I started reading the chapter 11 (Ajax) and, at some points, I think that understood well, but there is one example that confuses me. Let's look at an example from the beginning of the book: I didn't really understand the purpose of this. If AJAX was used when user fills some fields like username, that would make sense. For example, when user enters username and onblur event happens - than AJAX will be used to "do the job" and that would save some time for that user if he entered username that alre
  13. Hello all, I am enjoying this book, and have had all success deploying the chapter 3 department select menu scripts on my local environment. When i try to implement the same when using a bootstrap style website, where the pages are outputted through the index.php file: https://mysite.com/index.php?page=dept_form&did=1 I run into problems. In your book on chapter 3 your dept.js file has the code pulling from (get, dept_results_ajax.php?did=' + encode...). Because of the bootstrap style site I am using will this be different? Also, does it matter if using https opposed to htt
  14. Hi, I can not figure out why the first example does not work. Also, I downloaded and tested code from this site - and it does not work... This example starts on page 433: Here is my ajax.js: function getXMLHttpRequestObject() { var ajax = null; if (window.XMLHttpRequest) { ajax = new XMLHttpRequest(); } else if (window.ActiveXObject) { ajax = new ActiveXObject('MSXML2.XMLHTTP.3.0'); } return ajax; } Here is my test.js: window.onload = function() { 'use strict'; var ajax = getXMLHttpRequestObject(); ajax.onreadystatechange = function() { if (ajax.readyState =
  15. Hi, I am using this extension to display the google map in my page. And i have a text field that have been adding dynamically. I want to display the text field values in the google map. How to pass the text field values into the google map functionality. view.php <div id="map_section"> <div class="country_travell" style="background-color: #F8F8F8"> <?php foreach($countriesTravelled as $i => $countryTravelled) { $isCloseRequired = ($i==0) ? false : true; $this->renderPartial('_country_travelled', array('countryTravelled'=>
  16. Hi, here is another problem I would like to get a hint or some thought of it. I get a group a datas from ajax response that I would like to append them into existing product listing. // ajax response that I want to inside into the product listing page <div id="category_thumbnail"> <a href="product_detail.php?pid=<?php echo $products['product_id'] ?>"> <img src="<?php echo $products['file_url_thumb'] ?>"><?php icon($products); ?></a> <p class="p_sku"><a href="product_detail.php?pi
  17. I have been making a menu to select primary category and ajax returns the subcategory. when I picks an option in subcategory category, the ajax then return the products under the subcategory. So far so good those steps do works. My next step is to click a specific product that is returned by Ajax response and have it calling ajax again to update its newsletter setting in the product DB. The problem here is that I am not able to select the product. Each product_sku have a <p>tag with a class "add_small". So I want to know any possible solution to deal this situation. thanks.
  18. I've been working through the book and really enjoying it. I'm thrown by the Contact Form example in the Ajax chapter. What it seems to be doing seems stupid, so I'm wondering whether I'm misunderstanding. The handleAjaxRequest function is defined on p. 458. It seems to specify that in case of an error, we submit the form again. The anonymous function that is called if the user clicks the submit button is defined on p. 459. It sends the Ajax request to the server. So if something goes wrong, we just try again? I thought perhaps we would send the form in a non-Ajaxy way, or som
  19. Hello nice people, I'm pretty new to the 'Yii' platform, however, I have searched all over the internet for a solution to my problem as I have had a roadblock on this for 3 days (believe it). I have a created form to receive employee data from user input. I have a 'textField' for password but my intention is to auto-generate this password using a custom method call. This call will initially fill the 'textField' automatically upon page load and subsequently require the use of 'ajaxButton' to re-generate a new password. As it stands, the method is located in my Model, while my controller is
  20. Hi to all, Somewhere in the book Larry shows how to write a simple progress indicator for the user. It counts the %99 of time remaining until a task is complete. It might have been during an AJAX call. That's my purpose. If anyone can find this and provide the page number, please reply. I can find it in the index or by skimming. And I never miss a chance to say thanks again Larry. With your help, I am coding AJAX with little web app experience. Your books are phenomenal! Thanks in advance, CanuckCoder
  21. Have a situation where - when submitting form data to a php script - the ajax script stalls at: ajax.send(data); When the script stalls, it throws no error messages and returns no results. It just stalls. The php script runs all of its scripty things perfectly sans ajax, so I know the php and mysql is solid. It's just when it comes to incorporating the ajax that there is any issue. But wait - there's more. When the script is under the influence of ajax, and stalls, the Firebug console displays this line of text in red (red obviously indicating some kind of error, even though there's
  22. Hi Larry, I regularly use the move_uploaded_file function as described in chapter 11 of the book. However the other day I wanted to use it in a form the data of which gets processed via a JQuery AJAX POST call. The form enables the user to select a file for uploading and I was wanting the AJAX-called PHP script to then process it including the move-uploaded_file logic. But it seems that the $_FILES super global values are not visible to the AJAX-called PHP script. Does this sound right? FYI the $_FILES data are visible if I use your technique where the form script calls itself w
  23. Hi Larry, Great fan of you books! I've recently gone over Chapter 11 and I had a question regarding passing data from JSON to PHP using the code provided in the book for test.js (434-436). I've modified the script to use JSON and that works beautifully. I'd like to know if there is a clean JS solution to pass data to PHP without relying on jQuery.ajax({ data })? I've looked everywhere for a solution but the solution seems easily resolved with jQuery, but I'd like to avoid that if possible. Here is the code I've used as dictated in the book: window.onload = function() { 'use str
  24. Hi everybody. I have used the following code from http://www.yiiframework.com/wiki/361/simple-way-to-use-autocomplete-using-different-id-and-display-value/ . My table name is dog and I'm interested in three attributes: id, name and size. So far I have gotten an autocomplete field working which is populated with the name-attribute values as typed in by the end user. The following code does that: Under extensions: <?php Yii::import("zii.widgets.jui.CJuiAutoComplete"); class myAutoComplete extends CJuiAutoComplete { /** * Run this widget. * This method registers
  25. Hi. I was just wondering how facebook does it's continious updates on the wall if you know what I mean, I take it after a certain amount of time it calls a scripts which then gets the latest round of updates. So what technologies would be used here ? and also how would you stop it from repeating it's-self(i.e. calling the same data from before) ? Also does anyone know of any examples of this ? Regards
