Question

I’m working on pagination, and for some reason I cannot use mysql_fetch_array to loop through a result more than once.

//both $page and $imagesPerPage != 0
$offset = $page * $imagesPerPage
while ($row = mysql_fetch_array($result)) {
   $total_images++;
}
echo $total_images;
//echos correct amount
$row = null;


$images_to_offset = 0;
while ($row = mysql_fetch_array($result) && $images_to_offset < $offset) {
   $images_to_offset++;
}
echo $images_to_offset;
//echos 0... which is wrong

Should I be using a different php function to get row data in a database?

Thanks!

Answer 1

This is the error

while ($row = mysql_fetch_array($result)) {
   $total_images++;
}

once you fetched the array the array pointer set to the end.

use this

 $total_images=mysql_num_rows($result);

and

$images_to_offset=mysql_num_rows($result);

OR

To reset the position of pointer Use mysql_data_seek(). it moves internal result pointer
