I loaded PEAR successfully and loaded the the required packages but when I run login.php I get "Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\bin\php\php5.4.3\pear\Auth.php on line 469" and a "Strict standards: Non-static method DB::isConnection() should not be called statically, assuming $this from incompatible context in C:\wamp\bin\php\php5.4.3\pear\Auth\Container\DB.php on line 150" error. Would you be able to explain this pls? I am on a win7 system and a WAMP server.

I have been to the PEAR website but find the installation instructions a bit vague. Is there another site that has in depth instructions for newbies? rgds

Hi Would you be so kind as to break down and explain the following: // Delete old sessions: $q = sprintf('DELETE FROM sessions WHERE DATE_ADD(last_accessed, INTERVAL %d SECOND) < NOW()', (int) $expire);

Hi Sam. this link takes me to PHP 6 and MySQL 5 for Dynamic Web Sites: Visual QuickPro Guide (3rd Edition) Regarding the problem I have. What i have done to try and debug is copied the style.css file into my includes file (as directed by the file structure in the book pg 54) and into a style folder that I created as the code directs <? <head> <title><?php echo $page_title; ?></title> <link rel="stylesheet" type="text/css" href="style/style.css" title="style" /> </head> ?> and still the css is not loading. I have gone back to 'PHP and MySQL for dynamic websites' book and also went through my working examples and that too has led me nowhere. What I have now done is gone to the website 'www.HTML5webtemplates.co.uk', downloaded another template and that HAS WORKED fine. So I assume that there is something wrong with the CSS file in the .zip file that I downloaded? pls advise

I am busy with the chapter 2 templates section and my html template example does not look like the example in the book (header.html). I have loaded the css file. The footer seems to be ok. Is there an issue with the CSS template? or do u perhaps have a working example online?

Hi I would like clarification on when to use echo and when to use print_r(). Also the 2 aurguments print_r() takes. I understand the variable $students but not the 1 in <? print_r($students, 1); ?>

Regarding data validation and sanatizing, would it be considered wise to use HTML5 and Javascript data validation functions together with PHP data validation/sanatizing functions? I would think yes BUT I am concerned and don't understand what implications it could have on a production site.

I understand why one would use the ($_SESSION['agent']), what I would like to ask though is why , in the conditional <? if (!isset($_SESSION['agent']) OR ($_SESSION['agent'] != md5($_SERVER['HTTP_USER_AGENT']) )) { ?> you would use OR and not AND. I would think that you would check for both?
-
thank you
-
Ok, I understand, makes sense. Could I just ask, why would you also add $dbc? Why not just email and pass?

I have completed 'PHP and MySQL for Dynamic Web Sites Visual Quickpro 4th Edition' (well, almost done, I am on the last chapter) and I was wondering if, regarding this book, I can start on ch 6 'Basic OOP' or do you recommend I start from chapter 1?
-
ok, where would I find the guidelines?

Php And Jquery
kwandoa replied to kwandoa's topic in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)
Great!!! awsome, now i understand!! I would like to use this method to validate forms and to play around with what HTML elements to load, depending on the user. -
How would one pass a php variable to a jQuery function. I would like to use jQuery to only show the delete and edit links if $_POST['user_id'] =1. // Table header: echo '<table align="center" cellspacing="0" cellpadding="5" width="75%"> <tr> <td align="left"><b>Edit</b></td> <td align="left"><b>Delete</b></td> <td align="left"><b><a href="view_users.php?sort=ln">Last Name</a></b></td> <td align="left"><b><a href="view_users.php?sort=fn">First Name</a></b></td> <td align="left"><b><a href="view_users.php?sort=rd">Date Registered</a></b></td> </tr> '; // Fetch and print all the records.... $bg = '#eeeeee'; while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) { $bg = ($bg=='#eeeeee' ? '#ffffff' : '#eeeeee'); echo '<tr bgcolor="' . $bg . '"> <td align="left"><a href="edit_user.php?id=' . $row['user_id'] . '">Edit</a></td> <td align="left"><a href="delete_user.php?id=' . $row['user_id'] . '">Delete</a></td> <td align="left">' . $row['last_name'] . '</td> <td align="left">' . $row['first_name'] . '</td> <td align="left">' . $row['dr'] . '</td> </tr> '; } // End of WHILE loop. echo '</table>';

My form loads ok. login.php everything works like it should EXCEPT that when I submit the form with no password value I get the followoing error: Notice: Undefined variable: p in C:\EasyPHP\www\basicMySql\includes\login_functions.inc.php on line 41 But if i fill in a value, even a false one, the code works fine. could it be something to do with my isset()/empty() function?
-
list ($check, $data) = check_login ($dbc, $_POST['email'], $_POST['pass']); Regarding the above. would you be able to go into a bit more detail. Another thing ... PHP.net states that it is not really a function "Like array(), this is not really a function, but a language construct. list() is used to assign a list of variables in one operation." - php.net

I have uninstalled and reloaded easyPHP and it does run it now BUT it does not show the file (header.html) in the EasyPHP admin page . It does show all the other files, including the 'h1.html'. If I go to the folder via windows7, i can see it... so i'm thinking it's an EasyPHP glitch...I can live with it for now.

I guess you've been asked this many times...but amuse us this one time. In your opinion, if you met a beginner web developer and had to advise him/her on what Web Developing language to begin with, keeping in mind the Framework applications that are out there. Would you recommend PHP or Ruby?
-
OMG! that was so obvious, maybe I should step away from the computer for awhile and take a break LOL. I take it then , that I cannot run the code without completing the login.php....

I am not getting the desired results from the login lesson : Cookies and Sessions page 375 when i try and run http://127.0.0.1/basicMySql/includes/login_page.inc.php I get the form, which I complete BUT when I submit it I get taken to a http://127.0.0.1/basicMySql/includes/login.php which I have deleted from my directory(I am redoing this chapter which I did not get right the first time around). Would this be a cache problem?
