I have a little problem in my code, please review it and help me.
I want to assign value of the span tag(fetched by id in html) to a php variable and then run a sql query to fetch record of the related value in the table. Here is my code.
I tried it in different ways but it not works.
I print the sql query and its absolutely right but does not show the correct result. I copied that printed sql query and paste it into phpmyadmin query section and run it there. Then it works fine and show related records. Please help
$regg = '<span id="modal-myvalue"></span>';
$fee_detail = "SELECT * FROM `fee_enroll` WHERE registeration = '$regg' AND mode = 'ENABLE'";
//here i print the query and its output is correct but doesn't show the correct record here.
echo $fee_detail;
$result_fee = mysqli_query($con, $fee_detail);
while($row_fee = mysqli_fetch_assoc($result_fee)) {
echo $row_fee['registeration'];
}
The data which i want to fetch in span tag(in id) is sent from a button through this script:
<script type="text/javascript">
var ATTRIBUTES = ['myvalue'];
$('[data-toggle="modal"]').on('click', function(e) {
var $target = $(e.target);
var modalSelector = $target.data('target');
ATTRIBUTES.forEach(function(attributeName) {
var $modalAttribute = $(modalSelector + ' #modal-' + attributeName);
var dataValue = $target.data(attributeName);
$modalAttribute.text(dataValue || '');
});
});
</script>
and the button code is
<a class="btn" type=submit data-toggle="modal" data-target="#model-view" data-myvalue="<?php echo $row['registeration']; ?>">VIEW Detail</a>
When i print the query it shows:
(SELECT * FROM `fee_enroll` WHERE registeration = 'FA12-BSE-094' AND mode = 'ENABLE')
which works correctly in phpmyadmin query section. but not works here when i want to execute.

You can try DOMDocument as follows,
And then you can use this variable in query like below,
You cannot insert a variable like that. See this answer.
Curly braces in string in PHP
My suggestion should be to change the query string into the following:
$fee_detail = "SELECT * FROM
fee_enrollWHERE registeration = '{$regg}' AND mode = 'ENABLE'";
