Question

I have a php script which is editing records in mysql table. I have an issue in refreshing the page using javascript by passing the record number.

Pl check below are the few lines of my php script:

if ($mode == "edit")
{
$ids=$_POST[prs_rid];
$edt1=mysql_query("SELECT * FROM ECRDTL_edit WHERE id='$ids'");
$edt2=mysql_fetch_assoc($edt1);

echo "<script>var x=document.getElementById('prs_rid').value</script>";
    echo "<script> alert (x);</script>";
echo "<script>document.location.href='ecr-detail-edit.php?prs_mode=edit&prs_id='+x;</script>";
}

I have used alert to see if variable “x” is getting the record value or not, this works fine. But when i use the same in the next line, it is not showing the same record in the edit mode of my php.

But if I put the same line in address bar of a browser like this, it works fine:
http://www.mydomain.com/ecr-detail-edit.php?prs_mode=edit&prs_id=27

Kindly check what could be the issue or is there any other way of refreshing the page passing the record number.

Answer 1

Relative URL’s don’t work when assigned to location.href, it should be absolute or fully qualified.

In your case, absolute will do:

location.href = location.pathname + '?prs_mode=edit&prs_id=' + 
    encodeURIComponent(x)

The location.pathname gives the path (starting with /) up to the query separator (question mark).

I’ve also added encodeURIComponent(x) to make sure the value of x is properly escaped if necessary.

Implementation

echo "<script>location.href = location.pathname + '?prs_mode=edit&prs_id=' + encodeURIComponent(x);</script>";
