I am learning PHP and trying to make one admin panel. I have a link like below in my table.
<i class="icon-eye"></i>
when clicking on the above link icon, it's opening one modal form, in that form I want to show all details of user of that row id from the table. I have my modal code and PHP code like below
<div id="modal_form_vertical" class="modal fade" tabindex="-1">
<?php
$users1_qry="SELECT * FROM users WHERE id = 1";
$result1=mysqli_query($mysqli,$users1_qry);
$row1=mysqli_fetch_assoc($result1);
?>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header bg-primary">
<h5 class="modal-title">More Details</h5>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<form action="#">

<div class="modal-footer">

</div>
</form>
</div>
</div>
</div>
You can see currently I have used 1 as user id in my mysqli query because I don't know how I can I pass row id to this modal class and so I can retrieve and use it. Let me know if someone can help me for same.
Thanks

You can send the ID by using POST or GET method, save it in the variable in your script and then use in the sql query.
Example:
<?php
$id = $_POST['id'];
$users1_qry="SELECT * FROM users WHERE id =".$id;
$result1=mysqli_query($mysqli,$users1_qry);
$row1=mysqli_fetch_assoc($result1);
?>
Consider using prepare/execute method so that you prevent possible SQL injections.
