  1. $dbValue = the value stored in the database. <select name="colours"> <option value="blue" <?php if(isset($dbValue) && $dbValue == "blue") echo "selected"; ?>>blue</option> </select> You can use the same principle to pre-populate radio buttons.
  2. For select (drop-down list) you can preset a selection using "selected": <select name="colours"> <option value="blue" selected>blue</option> </select> For radio buttons you can preset a value using "checked": <input type="radio" name="status" value="on" checked>On So you need to compare the value you have stored, against the value of each option and then include selected or checked in the html for that element.
  3. The first thing you need to do is place the instantiation of the SoapClient object within a try catch block. This will help you problem solve the issue you’re having with your script. There is a lot of information online about writing services using PHP. I have no idea where you are in terms of you level of PHP knowledge/learning and I could be doing you a huge disservice by stating get good at searching for information/tutorials online. I had a quick search on google and I got a huge number of useful resources for tutorials; sitepoint seems to have a pretty good 2 part series: creatin
  4. I think your issue is that you're trying to type hint float on a number that isn't a float: $curtain_price_total. (float)1,234.45 Floats don't have commas. Personally, I would store price as integers in the DB and then format as and when required in your scripts.
  5. Yeah, this was tedious when I first started using vagrant, until I found that you could suspend a guest machine: https://docs.vagrantup.com/v2/cli/suspend.html vagrant global-status is also really handy to manage/see all the guest machines. https://docs.vagrantup.com/v2/cli/global-status.html
  6. I'm Just curious, but is there a reason you've decided not to offer subscription billing. Getting users to log in monthly and make a payment is tedious for them. Why not automatically charge each month and give them the option to cancel at any time?
  7. You’re looking at the wrong script. The issue is with the form script/page where your javascript makes a request to Stripe for a token which it then appends to the form before a post request is made to your payment processor script.

  9. Every coder should be striving to write the most legible code they can, for both themselves and others. Ask yourself how easily and quickly could you read and understand what the code does if you came back to it in 6 months. My view is, always use curly braces. Also, understand that projects often have their own code style rules. I have my own preferences but I’ve found myself having to write code differently because I wanted to contribute to certain open-source projects. I’d recommend having a look at PSR http://www.php-fig.org/psr/psr-1/ “Always code as if the person who ends
  10. Larry, I think it was more me than the book; not helped by the fact I was reading the kindle version, which isn't always the best for layout.
  11. I'm having trouble understanding/linking the code example to the diagram and definition for the Factory Pattern. abstract class Shape { ... } class Rectangle extends Shape { ... } class Triangle extends Shape { ... } abstract class ShapeFactory { static function Create($type, array $sizes) { switch ($type) { case 'rectangle': return new Rectangle($sizes[0], $sizes[1]); break; case 'triangle': return new Triangle($sizes[0], $sizes[1], $sizes[2]); break; } } } $obj = Shap
  12. It's pretty straight forward to achieve. They're simply links with images instead of text. <a href="url_to_somewhere"><img src="icon.png"></a> There are lots of free social media icons available online, so unless you make your own it's just a matter of finding a free style that you like or fits with your overall design.
  13. I've used Twilio with both php and ruby - the api is insanely easy to use. There's some good info in the docs as well as many free tutorials on blogs etc.
  14. Or Curl, not sure it matters which method you use. This looks promising: https://github.com/KnpLabs/php-github-api The docs directory seems to have a pretty good list of examples If you share what you're trying to achieve I/we might be able to be a bit more helpful.
  15. The id you want to store in the db is not being submitted with your form. You need to include a hidden form field within your form, with the id value: <form ... > <input type="hidden" name="id" value="<? echo $id; ?>"> </form> You'll then need to assign the $_POST['id'] value to $id within your if ($_SERVER['REQUEST_METHOD'] == 'POST') { ... } conditional and before the db insert query. if ($_SERVER['REQUEST_METHOD'] == 'POST') { $id = $_POST['id']; # db query } Plus, what margaux said

    Cheers, Larry; that's really useful at the top of the page, thanks!
  17. This is really basic HTML CSS, wildman. If you're not comfortable with it I would recommend you pick up a good book or follow an online tutorial to learn the basics. As for your question, one div element should go around <a href="... > <img src="... > </a>, but you're not even doing inline css styling correctly: <div style="width: 33%; float: left;">
  18. Ghamdan, you don't say which method you're using to select part of the string, also did you look at the link I provided?
  19. Have you bought Larry's book? I'd say that's a pretty good place to start.
  20. You need to put the <div> tags around each of the links with images, not one around all three.
  21. Check you're using the same character sets, also have a look at the following if you're still having issues: http://php.net/manua...n.mb-substr.php

    Yeah, the removal of latest topics/comments on the main forum page for non-logged-in members or visitors now forces users to sign up and log in to get that functionality. Personally, I don't want to have to log in unless I'm actually starting a topic or posting a comment; I doubt I'm unique in this.
  23. Have a read through chapter 7: https://cms.paypal.c...rationGuide.pdf
