Heya, Kumuda.

You can display a PHP variable in a textbox like this:
[code=html]
<textbox><?ph p echo $variable; ?></textbox>
[/code]

If you absolutely need to transport the PHP variable to Javascript, simply create JavaScript code to generate the variable:
[code=php]
echo '
<script type="text/javascript">
// <![CDATA[
var myVar = "' . $variable . '";
// ]]>
</script>';
[/code]

No need to go with java script....try this
[code=php]
<?php
$i='value';
echo '<input type="text" value ='.$i.'>'
?>[/code]

AMT, please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

Hi pbmods,

I tried the code
[code=html]
<script language="javas cript">
/ <![CDATA[

var myVar = "' . $Name . '";
alert(myVar);

// ]]>
</script>
[/code]

But this is not working, it is just displaying the '.$Name.' but the contents of variable. Please help me.

With regards

Hi.

PHP and JavaScript do not work together. PHP is executed Server-side before your JavaScript code is executed on the client's browser.
You need to use PHP to generate the JavaScript code.

Like this:
[code=html]
<script language="javas cript">
/ <![CDATA[

var myVar = "<?php echo $Name; ?>";
alert(myVar);

// ]]>
</script>
[/code]

Hi all,

I have one more issue.

I want to add one option dynamically to dropdown box i.e. it will get the value from another page on clicking a link and it should add that value to existing list of dropdown box values.
I have used the following code where 'SelectSP' is the name of the dropdown box
[code=javascript]
<script language="javas cript">

var Name = "<?php echo $name; ?>";
document.getEle mentById('Selec tSP').value=Nam e;

</script>[/code]

You can use PHP to dynamically build your dropdown box.

Consider this code:
[code=php]
<select name="mySelect" >
<?php
for($i = 0; $i < 3; $i++) {
echo "\n\t<optio n value=\"$i\">It em #$i</option>";
}
?>
</select>
[/code]

Which would output something like this
[code=html]
<select name="mySelect" >
<option value="0">Item #0</option>
<option value="1">Item #1</option>
<option value="2">Item #2</option>
</select>
[/code]
