Question

 document.write('<iframe  src=\"{<?php echo $row1['details']; ?>}\"</iframe>');

I'm trying to create an iFrame to be display using this javascript code, however when the code is executed, I can visually see the frame however, the frame is mirroring a 404 (Page Not found) error. Why's this?

Answer 1

<?php echo $row1['details']; ?> <?php echo $row1['details']; ?> has got a ' while the outter function uses ' and ' to start and end its string. You'd have to do such as: <?php echo $row1[\\'details\\']; ?> <?php echo $row1[\\'details\\']; ?> . Next time please provide more code and describe your issue.

Also, you were missing a > .

document.write('<iframe  src=\"{<?php echo $row1[\'details\']; ?>}\"></iframe>');

<form id="process_page" name="process_page" method="post" action="cms.php">
<select name="product" id="product"  onchange=prod(this.id)>
<option value="">------</option>
<option value="A">A</option>
</select>
</form>



 <?php 
$srv_vame="localhost";
$usr_name="root";
$pswrd="";
$udb="dt";
$sql_conn=mysqli_connect($srv_vame,$usr_name,$pswrd,$udb);

$f_ssql="select * from  category";
$fsql=mysqli_query($sql_conn,$f_ssql);
$row1=mysqli_fetch_array($fsql);
?>


<script type="text/javascript">

function prod(e)
{
var e=document.getElementById(e);
var AB =e.options[e.selectedIndex].value;
if(AB == 'A')
{
document.write('<iframe  src=\"{<?php echo $row1['details']; ?>}\"></iframe>');
}

}
</script>
