**ufo973** · 05-03-2008, 11:19 AM

Hello
for 5 hours i am trying to figure out this strange problem but can't so i came here if any one of you can solve it.

What i want to do is get the text value of a SELECT by javascript then asseign it to a php variable and insert it in the mysql database
everything works fine but when i go to mysql and chekck the entry it is strange. even if i echo the variable in page it is showing the value and ok but when i check it in the database it is something like this.
<script language=javascript>document.write

Here is my page...

<html>
<body>

<form name="form1" method="post" action="">
<select name="select">
<option value="1">a</option>
<option value="2">b</option>
</select>
</form>

<?php
//asseigning the javascript variable to php
$MyVar1 = "?><script language=javascript>document.write(document.form1. select.options[form1.select.selectedIndex].text);</script><?php";
$MyVar1 = str_replace("?>", "", $MyVar1);
echo $MyVar1."<br><br>";//works fine

$host="localhost";
$user="root";
$pass="";
$db="hr_mysql";

$con=mysql_connect($host,$user,$pass);
if($con){
echo "Mysql Connected <br>";
}
else{
echo "Mysql connect error<br>";
}

$sel=mysql_select_db($db,$con);
if($sel){
echo "DB Selected<br>";
}
else{
echo "DB Select error<br>".mysql_error();
}

$sql="insert into hs_mustafa_modify values ('$MyVar1')";
$res=mysql_query($sql);
if($res){
echo "successful"; //successfuly enteres in database
}
else{
echo "Sorry ".mysql_error();
}

mysql_close();

// now go check it in the database for miracle.
?>

</body>
</html>

It's Saturday and 30 minutes later.

Apart from that it can't be done. PHP code is run and finished with, before the javascript even gets started.

the variable actually taking the javascript code , so the database get s the javascript code.

the reason might be the value is not assigned to variable.

I think your problem is that you're expecting to intermingle JavaScript and PHP. You just can't do that, as chrishirst pointed out. PHP is a server side language that is interpreted before the page is ever sent to the browser.

JavaScript, on the other hand, is a client-side language that processes things within the confines of the current environment, usually a browser. If you need some PHP processing to happen, you can dynamically post values to a PHP page from a JavaScript function. That may be what you want to look into. Just do a google search for AJAX.

You dont need javascript to process a form...
