Hello,
how can do <? $a = <font id="e9"></font>; ?>

 

Maybe <? $a = "<font id=\"e9\"></font>"; ?>

 

Try this:

 <?php

    $a = "<font id='e9'></font>";

 ?>

PHP:

or if you are doing error messages you can do this

 <?php

   $aOpen = "<font id='e9'>";
   $aClose = "</font>";

 ?>

PHP:

Then just echo out your message, here is an example.

 <?php

   $aOpen = "<font id='e9'>";
   $aClose = "</font>";

     echo $eOpen . "Here is the information you are echoing out." . $eClose;

 ?>

PHP:

Your question is unintelligible. I'll take a stab at it anyway, is this what you're talking about?

<?php
    $html = "<font id='e9'></font>";
    preg_match("/<font\sid='.(\d+)'/i", $html, $matches);
    $a = $matches[1];

    // you now have $a to play with..
    echo $a;
?>

PHP:

Ahh, ok. I think I understand now.

In order to pass data to the PHP script (and subsequently MySQL), you will either have to create a form and have your JavaScript events change the value of one of the fields (this could even be a hidden field) or create an Ajax call that passes everything to the script.

So, here is the example HTML:

<form action="t.php" method="post" id="settingsForm" name="settingsForm"> 
	<input type="hidden" name="special_discount" id="special_discount" value="0" /> 

	<p>
		<label> 
			<input type="radio" name="vip" value="2" id="v" onclick="calcadv()" />1 </br> 
			<input type="radio" name="vip" value="3 id="v" onclick="calcadv()" />2</br> 
		</label>
	</p> 

	<p>
		<label> 
			<input type="radio" name="week" value="2" id="w" onclick="calcadv()" /> 1 </br> 
			<input type="radio" name="week" value="3" id="w" onclick="calcadv()" /> 2</br> 
		</label>
	</p> 

	<p>
		<label>
			<!-- This field has been added -->
			<input type="hidden" name="result" id="result" />
			Total: <font id='p7'></font>
		</label>
	</p> 

	<p> 
		<input class="button" type="submit" value="Изпрати" name=saveu /> 
	</p> 
</form>

HTML:

Now the JavaScript function you use to to calculate the result would also put said result in the hidden field:

function calcadv() {
	// All of your code here...
	
	// assuming 'result' is the right variable
	document.getElementById("result").value = result;
}

Code (markup):

And finally, in PHP you could see this by looking at $_POST['result'].

 

Not work
Can a $ _POST take info from <div or <span ?
example
<div id='p7' name="result" ></div>
$as = $_POST['result']

 

No, it has to be a form field. Which can either be <input> or <textarea>.
