Problem with embedding JS code in PHP

Hi all,

I have the following string as part of my PHP code (before you ask, it HAS to be in PHP, can't write PHP and HTML separately):


   $submission_form ="
    <p style=\"font-size:20px; padding: 15px;\">
      <u>Please select the type of analysis you wish to perform</u>
    </p>
    <form name=\"analysis_form\" method=\"post\"> 
    <div>
      <a id=\"myHeader1-2\" href=\"javascript:showonlyonev2(\"newboxes1-2\");\" >
        <input type=radio name=\"criterion\" value=\"single_genotype\">
        Single-study analysis using genotypes
      </a>
    </div>

Everything works fine, except the JS part...Because it should have single quotes, but this I can't do it inside the PHP string...
Any ideas?

You could use "heredoc" syntax to avoid all the escaping:


$str = <<<EOD
<html code goes here>
EOD;

Hi, yes, I tried that but still I get error:


$submission_form = <<<EOD
 <p style="font-size:20px; padding: 15px;"><u>Please select the type of analysis you wish to perform</u></p>
 <div>
  <form enctype="multipart/form-data" name="analysis_form" method="post" action="single_analysis_gen.php"> 
  <a id="myHeader1-2" href="javascript:showonlyonev2('newboxes1-2');" >
   <input type=radio name="criterion" value="single_genotype">
   Single-study analysis using genotypes
  </a>
 </div>
 </form>
EOD;

It works OK if I remove the

 href="javascript:showonlyonev2('newboxes1-2');"

part...

What error do you receive? The above works fine for me. Which PHP version is it?

You can if you enclose your variable's value with "double quotes", as you do, or vice versa.

$variable = "<a id=\"myHeader1-2\" href=\"javascript:showonlyonev2('newboxes1-2');\">";

$variable = '<a id="myHeader1-2" href="javascript:showonlyonev2(\'newboxes1-2\');">';
