Hello so I am having a slight problem at the moment Basically I have a while loop that outputs a table called job from database along with a bid button that links to bid.php. When the button takes me to the page I want it to carry over the jobid of the row that the button was clicked so I can enter the specific value into my database does anyone have any ideas on how to move over currently I am trying to do it using POST but I keep getting errors and the variable dosnt seem to be moving over.I just get a blank page and the id is not displayed.
Here is findjob22.php:
<?php
require 'config.php';
if(isset($_POST['submit']))
{
$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT * FROM `job` WHERE CONCAT(`job_id`,`location`, `description`, `budget`, `duedate`,`title`) LIKE '%".$valueToSearch."%'";
$search_result = filterTable($query);
}
else {
$query = "SELECT * FROM `job`";
$search_result = filterTable($query);
}
// function to connect and execute the query
function filterTable($query)
{
$conn = mysqli_connect("localhost", "root", "", "bid4myjob");
$filter_Result = mysqli_query($conn, $query);
return $filter_Result;
}
?>

I am not sure you can pass values in the submit button, but you can use a hidden input to pass the value.
<input type="hidden" value="<?php echo $row['job_id']; ?>" name="job_id" />
<input type="submit" class="btn btn-xlarge btn-block btn-primary">bid</input>
If you want it to work like you have it use a button.
<button type="submit"
name="job_id"
value="<?php echo $row['job_id']; ?>"
class="btn btn-xlarge btn-block btn-primary">
bid
</button>
if you want to also pass some data:
<form method="post"
action="bid.php"
class="form-horizontal">
<div class="input-group">
<input type="text"
class="form-control"
name="bid"
id="bid" required />
</div>
<button type="submit"
name="job_id"
value="<?php echo $row['job_id']; ?>"
class="btn btn-xlarge btn-block btn-primary">
bid
</button>
<br/>
</form>
Then you will have a $_POST["job_id"] and $_POST["bid"] in bid.php

Quick rundown:
Everything ran perfectly as it should when I had my own custom textarea field to send data
I had a custom text editor widget for inputs, but tried to add CKEditor for more functionality
When I added CKEditor package (https://ckeditor.com/ckeditor-4/download/?undefined-addons=) the editor was there, but when I clicked "Add" button and sent data, the input was doubled and there was a space between inputs (for example - input was:"test" and output was "test<br><br>test"), as if I put <br> tag and multiplied my input somewhere.
When I stopped trying with CKEditor, I went back to original code and my own original custom text editor, which before worked perfectly. However, to my surprise, it now still doubles the input string, but it doesn't put a <br> tag in between.
In DB the string value is normal and not doubled.
I have no idea how this happened, I've been going over the code for a hour or so now, trying to see if I overlooked something, but I even created a separate file with functioning code, before I was trying with CKEditor in case something broke and I could just replace it with old code and try tomorrow, but now it's messed up and I have no idea how and where.

The problem was with the <?= syntax (echoing), <?php solved it.
I wanted to delete a row in mysql phpmyadmin database through a button in AssetApprovalForm.php, but when I clicked on the decline button in AssetApprovalForm.php nothing happens.
This is the image for AssetApprovalForm.php
This is my code in AssetApprovalForm.php
<form action='delete.php?SN="<?php echo $SerialNumber; ?>"' method="post">
<div class="row">
<div class="col-sm-6">
<div class="inputfield">
<input type="text" id="decline" name="decline" value="Decline" class="btn" >
</div>
</div>
</form>
<div class="col-sm-6">
<div class="inputfield">
<input type="text" id="submit" name="accept" value="Approve" class="btn">
</div>
</div>
</div>
I have included JavaScript in my AssetApprovalForm.php to perform a pop up after the button is clicked.
<script>
$("#decline").click(function(){
swal("Bruh!", "This ticket has been declined", "error");
});
</script>
<script>
$("#submit").click(function(){
swal("Nice!", "This ticket has been approved", "success");
});
</script>
This is my code for delete.php
<?php
include 'db_connection.php';
$SerialNumber = $_GET["serial"];
$query = "DELETE * FROM waiting_approval WHERE SerialNumber = '" . $SerialNumber . "'";
if(mysqli_query($conn, $query))
{
mysqli_close($conn);
header('Location: AssetApprovalList.php');
exit;
}
else
{
echo "Error declining request";
}
?>
Current:-
<div class="col-sm-6">
<div class="inputfield">
<input type="decline" id="decline" name="decline" value="Decline" class="btn">
</div>
</div>
<div class="col-sm-6">
<div class="inputfield">
<input type="text" id="submit" name="accept" value="Approve" class="btn">
</div>
</div>
I think your input type is wrong it should be type="text" not type="decline"
and for submit button it should be type="submit" not type="text"

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..

I'm trying to populate a drop down from values in DB on the same page which is from input on the same page itself.
I have tried a few options on the forum but it did not help.
After hitting submit it goes to a next page which is blank.
I have tried onchange=AjaxFunction(); as suggested in one post, but i still get a blank page.
Any help is appreciated.
This is my form.php

This is the best I can do with the information provided.

I can't work it out, spent hours looking online... My concern is at it's using Bootstraps Modal I wasn't sure if it would be able to grat the POST data... As if I enter the ID manually it works...
Any assistance would be greatly appreciated.
change this
$id=isset($_POST['id_grab']);
to
$id=isset($_POST['id_grab'])?$_POST['id_grab']:'';
//if id_grab dont have a value then $id value will be ''
isset() Returns TRUE if var exists and has value other than NULL, FALSE otherwise.
