[CoderJohan]

I have a guestion about intigrate PHP into a javascript and how i'm suppose to do that. Like i have this code

<Javascipt>

</script>

but i wan't to do this

<Javascipt>

<?php
some php code
?>
</script>

How can i manage to do this i wonder?

My suggestion would be to echo out your javascript code using php, like

echo "<javascript>javascript code here</script>";

When you come to PHP, break out of the echo statement and simply put in your necesssary PHP code, like:

echo "<javascript>";
echo "some javascript code here";
echo "more javascript code here";
if (some_php_code) {
     echo "This is cool!";
}
echo "</script>";

As i suspected... Time to write alot of Echo then 🙂

Erm... just to clarify: you don't need to echo a single line at a time 😉
That is, you don't need a separate echo-statement for each line, as viewed.
Here's a multiline code:

<?PHP
echo "
<table width=\"437\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\">
<tr>
<td width=\"135\" align=\"left\" valign=\"top\">
<span class=\"tdHead_red2\">Status:</span><br>
<table width=\"135\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\">
<tr><td width=\"110\" align=\"left\" valign=\"top\"><span class=\"utilitariantext6\">Registrerte brukere:</span>&nbsp;</td><td width=\"25\" align=\"center\" valign=\"middle\"><span class=\"utilitariantext2\">$memkcount&nbsp;</span></td></tr>
<tr><td width=\"110\" align=\"left\" valign=\"top\"><span class=\"utilitariantext6\">Online registrerte:</span>&nbsp;</td><td width=\"25\" align=\"center\" valign=\"middle\"><span class=\"utilitariantext2\">$loguonlinecount&nbsp;</span></td></tr>
<tr><td width=\"110\" align=\"left\" valign=\"top\"><span class=\"utilitariantext6\">Antall innlegg:</span>&nbsp;</td><td width=\"25\" align=\"center\" valign=\"top\"><span class=\"utilitariantext2\">$postucount&nbsp;</span></td></tr>
<tr><td colspan=\"2\" align=\"left\" valign=\"top\"><span class=\"utilitariantext6\">Sist&nbsp;reg:</span>&nbsp;&nbsp;<a href=\"forum.php?forum_control=memview&member=$id\" class=\"utilitariantext1\">$username</a></td></tr>
</table>";
?>

But I guess you knew that 😃

Yes, sorry, as Mogster pointed out, you don't need to echo a single line at a time.

I just do this so I can see how the HTML or Javascript code lays out.

To avoid commenting out all of the ' and ", in most situations you can just print your JavaScript as-is and only insert the PHP where necessary.

This is what you might do to change a popup javascript box based on factors that are determined by PHP.

<script language="JavaScript">
<!--
function MM_popupMsg(msg) { //v1.0
  alert(msg);
}
//-->
</script>

<?
//Run your code that will alter the javascript
if($whatever=="your conditions or code or whatever"){
    $foo="whatever you want foo to be.";
}else{
   $foo="something else";
}
?>

<a href="javascript:;" onClick="MM_popupMsg('<?=$foo?>')"><img border="0" src="myimage.gif" width="10" height="10"></a>

More code!

Here's the echo version, with a js that enables a multitude of forms to be submitted by link instead of buttons:

echo "
<SCRIPT language=\"JavaScript\">
function findSwitch_questions$topics[$f] ( selectedtype ) {
document.questions$topics[$f].forum_control.value = selectedtype;
document.questions$topics[$f].submit() ;
}
//-->
</SCRIPT>";

echo "
<table><tr>
<form name=\"questions$topics[$f]\" action=\"".$adr."\" method=\"post\"><td align=\"left\">
<a href=\"javascript:findSwitch_questions$topics[$f]('readquestions')\" class=\"utilitariantext1\">Read answers</a>
<input type=\"hidden\" name=\"selectctid\" value=\"$topics[$f]\">
<input type=\"hidden\" name=\"action\" value=\"details\">
<input type=\"hidden\" name=\"rule\" value=\"$rule\">
<input type=\"hidden\" name=\"forum_control\"></td></form>
</tr></table>";

For the POST-addicted with button-aversions....
