how to refresh tabs data when update table? - php

Question

index.php
<div class="tab">
<button class="tablinks" onclick="openCity(event, 'Engineering')">Engineering</button>
<button class="tablinks" onclick="openCity(event, 'LAW')">LAW</button>
</div>
<div id="Engineering" class="tabcontent">
<table class="items">
<tr>
<th>State</th>
<th>College Name</th>
</tr>
<?php
$query = "select * from college where field = 'engineering'";
$show = mysqli_query($link,$query);
while ($fetch = mysqli_fetch_array($show))
{
?>
<tr>
<td><?php echo $fetch['state']?></td>
<td><?php echo $fetch['college_name']?></td>
<td>
edit
</td>
</tr>
<?php
}
?>
</table>
</div>
<div id="Law" class="tabcontent">
<table class="items">
<tr>
<th>State</th>
<th>College Name</th>
</tr>
<?php
$query = "select * from college where field = 'law'";
$show = mysqli_query($link,$query);
while ($fetch = mysqli_fetch_array($show))
{
?>
<tr>
<td><?php echo $fetch['state']?></td>
<td><?php echo $fetch['college_name']?></td>
<td>
edit
</td>
</tr>
<?php
}
?>
</table>
</div>
edit.php
<?php
if(isset($_POST['update']))
{
$college_name = $_POST['colleges'];
$state = $_POST['state'];
$sqli = "update college set college_name = '$college_name', state = '$state' where id = '$id'";
$results = mysqli_query($link,$sqli);
if($result == true)
{
$msg .= "<p style='color:green;'>Your data update successfully</p>";
}
else
{
$msg .= "<p style='color:red;'>Errror!</p>";
}
}
?>
<form method="POST" enctype="multipart/form-data" >
<select name="state" id="state">
<option value="<?php echo $stateid; ?>"><?php echo $statename; ?></option>
<option value="">Select State</option>
<?php
$sql = "select * from statemaster";
$result = mysqli_query($link,$sql);
while($row = mysqli_fetch_array($result))
{
echo "<option value=".$row['stateid'].">".$row['statename']."</option>";
}
?>
</select>
<select name="colleges" id="colleges">
<option value="<?php echo $college_name; ?>"><?php echo $college_name; ?></option>
<option value="">Select College</option>
</select>
<button type="submit" name='update' id='update'>update</button>
</form>
In this code when I click on edit button then it will go to edit.php page where I get id from url and run update query after updating table college the data will update but when I move from edit page to index.php page the data will remain same but in database update data will be there. So, How can I fix this issue ?
Thank You

Check for caching. It could be that the browser is not going to the server in order to get the contents of index.php, as it thinks it has it.
Try calling index.php with a variable, like:
