  5. I want to know how I would go about making a script where a user would type in a message and post that said message. Is sql required?
  6. Hi All, I've seen that in PHP you can include a require or include function which saves you from having to add the entire code for headers and footers for each page. Does a similar things exist in HTML? If so, please direct me. Thanks in advance Russell
  7. I have used the W3 template to produce a script that uploads image changes to a directory on my server, updates the URL in my database and logs the event. Works beautifully IF the source folder is: \Pictures or \Pictures\Personal But fails if it is any other source folder, even the peer folder \Pictures\BarImages Why?
  8. In the lesson on PHP Filters in the code sample "Validate an Integer" there is the following code: <?php $int = 100; if (!filter_var($int, FILTER_VALIDATE_INT) === false) { echo("Integer is valid"); } else { echo("Integer is not valid"); } ?> Why use this expression: (!filter_var($int, FILTER_VALIDATE_INT) === false) instead of what seems to me to be the more logical expression?: (filter_var($int, FILTER_VALIDATE_INT) === true) Thanks.
  9. https://www.w3schools.com/php/phptryit.asp?filename=tryphp_filter_adv3 is a tutorial example. It attempts to validate what appears to be a valid URL but claims it is not. I see this forum gets little use, so has the language changed since the example was created, is there a mistake in the example, or is the problem on my end in the browser? I am using the latest FireFox browser under Windows 10.
  10. In PHP 5, I conventionally opened my pages with <?php but within the pages I often used <? to open a php block, e.g., <?echo $variable; ?>. In PHP 7, I find it is necessary to always use <?php and follow it with a space, e.g., <?php echo $variable; ?> I haven't been able to find any reference to this syntax change so my question: Is this a new requirement of PHP 7? Can it be turned off? Otherwise, I will need to edit all of the sites where my earlier habit was used, which I think I can do but would feel compelled to spend some hours testing afterward.

  14. At Ingolme's suggestion, I've switched from simpleXML to DOMXML for this because I need to be able to replace a node. I've done my best to follow PHP.com examples, and everything seems to work up until the point of the actual replacement. I hope you can spot what's keeping it from working. The vars found in the heredoc are assigned earlier from the customer input form. if $found is positive, it contains a cId (customer ID) that exists in the DB and should be updated with any new info (code shown). If negative, it's abs() is the cId for a new node to be added (code omitted here). In $xm
