I have some data in my mysql database which I am displaying in table using PHP like below
$requirement_qry="SELECT t1.*, t2.id as unit_id, t2.name as unit_name FROM `tbl_requirements`
t1 INNER JOIN tbl_units AS t2 on unit_type = t2.id AND project_id='".$_GET['project_id']."' AND user_id='".$userid."'";
$requirement_result=mysqli_query($mysqli,$requirement_qry);

Above code is properly displaying my data. I have one field value from row need to update using submit button. Its working fine if there only one row...if there multiple row, its not updating data of it except last row. My submit code is like below
if(isset($_POST['submit']) and isset($_POST['project_id']))
{
$projectId = $_GET['project_id'];
$data = array(
'unit_received' => $_POST['received']
);
$unit_edit=Update('tbl_requirements', $data, " WHERE id = '".$_POST['reqId']."'");
print_r($unit_edit);
echo $unit_edit;
if ($unit_edit > 0)
{
$_SESSION['msg']="11";
header( "Location:view_open_project.php?project_id=".$_POST['project_id']);
exit;
}
}
I am little new in PHP, Let me know if someone can help me for solve the bug. Thanks a lot :)
As @Saji has already stated, you are replicating your name through the loop.You should rather use
echo '<input type="hidden" name="reqId[]" id= "reqId" value="'.$id.'" />';
Note the []
brackets that were appended so that you create an array of names. To update, you need a loop like
for($i=0;$i<count($_POST['reqId']);$i++){
$unit_edit=Update('tbl_requirements', $data, " WHERE id = '".$_POST['reqId'][$i]."'");
}
What you can do is just create a hidden form where you will keep original elements. When the save button click you just find the actual value and set this to the elements inside hidden form, then trigger the submit button inside hidden form.
Note the changes I have done on your code.
1.Removed the hidden element reqId
from inside loop.
2.Given a class name to the button inside loop and changed the button type from submit
to button
. Added data attribute data-id="'.$id.'"
.
3.The input received
inside the loop has given unique id and name by concatenated the $id
.
4.Created hidden form with hidden input in it. It has your actual input names.
5.Created a jquery function to attach click event to the button inside loop.
6.Moved the hidden element project_id
to inside hidden form.
Now see the below code for more details. Hope this will help you..
