Question

I want to create PHP files dynamically. Static HTML code works fine, but when I want to insert PHP code, which contains a “window.location” command, my script directly send me to that page, without fulling the “if(isset())”-condition.

Somehow a simple echo doesn’t work. How can I fix this?

 public function suche()
 {
   echo "if(isset(\$_POST['searchit']))
   {
    \$suchbegriff = \$_POST['suchbegriff'];

    \$anfangsbuchstabe = substr(\$suchbegriff, 0, 1);

    <script type='text/javascript' language='Javascript'>window.location = '/".$anfangsbuchstabe."/".$suchbegriff.".php'</script>
  }";
 }

Answer 1

If you are really writing to a php file that you want to call / execute later in a different request, you need to make sure the php is recognized as php, now it is just text.

So you would need something like:

public function suche()
 {
   echo "<?php if(isset(\$_POST['searchit']))
   {
    \$suchbegriff = \$_POST['suchbegriff'];

    \$anfangsbuchstabe = substr(\$suchbegriff, 0, 1);
    ?>
    <script type='text/javascript' language='Javascript'>window.location = '/".$anfangsbuchstabe."/".$suchbegriff.".php'</script>
<?php
  }
?>";
 }

Note that I have added the php opening and closing tags.
