File view to the another tab (PHP) - php

Question

I have inserted a file with an UPDATE command because I want my files (pdf, jpg) to be in one table together with name, course, etc. and and I just want to know if it it is possible that instead of showing the name of the filename in the table, its filename would be an href on when the person have click it, it would go in the another tab to show is content (pdf, or jpeg).
Here is my code of my addrequirements.php
<?php
include_once 'connection.php';
$result = mysqli_query($conn,"SELECT * FROM collegestud");
$result1 = mysqli_query($conn,"SELECT * FROM shsstud");
session_start();
if(!$_SESSION['login']){
header("location:index.php");
die;
}
?>
<div id="ccc">
<?php
if (mysqli_num_rows($result) > 0) {
?>
<table id="example" class="display" style="width:100%;">
<thead>
<tr>
<th>Student Id</th>
<th>Course</th>
<th>Last Name</th>
<th>First Name</th>
<th>Psa</th>
<th>Form137</th>
<th>2x2 Picture</th>
<th>Actions</th>
</tr>
</thead>
<tbody id='cccc'>
<?php
$i=0;
while($row = mysqli_fetch_array($result)) {
?>
<tr>
<td><?php echo $row["Stud_ID"]; ?></td>
<td><?php echo $row["Course"]; ?></td>
<td><?php echo $row["Lastname"]; ?></td>
<td><?php echo $row["Firstname"]; ?></td>
<td><?php echo $row["PSA"]; ?></td>
<td><?php echo $row["Form137"]; ?></td>
<td><?php echo $row["Picture"]; ?></td>
<td><a style="color:green;" href="updatecollege1.php?id=<?php echo $row["ID"]; ?>"><i class="fas fa-folder-plus fa-2x "></i></a> 
<span><a style="color:red" href="deletecollege.php?ID=<?php echo $row["ID"]; ?>"onclick="return confirm('Do you really want to delete this student?')"><i class="fas fa-user-minus fa-2x"></i></a></span>
</td>
</tr>
<?php
$i++;
}
?>
</tbody>
</table>
<?php
}
else
{
echo "<p><center><strong>0 RESULTS IN THE TABLE</center></p></strong>";
}
?>
Code of my updatecollege1.php
<?php
include_once 'connection.php';
session_start();
if(!$_SESSION['login']){
header("location:index.php");
die;
}
$result = mysqli_query($conn,"SELECT * FROM collegestud WHERE id='" . $_GET['id'] . "'");
$row= mysqli_fetch_array($result);
?>
<div class = "container3">
<strong><left>PSA   </left></strong>
<span>   <input id="ra" type="text" value="" readonly>ADD or UPDATE</span><br>
Code of my psaadd.php
<?php
include_once 'connection.php';
session_start();
if(!$_SESSION['login']){
header("location:index.php");
die;
}
if(count($_POST)>0) {
mysqli_query($conn,"UPDATE collegestud
set PSA = '" . $_POST['PSA'] . "'
WHERE ID='" . $_POST['ID'] . "'");
$id = $_POST['ID'];
header('Location: updatecollege1.php?id='.$id);
}
$result = mysqli_query($conn,"SELECT * FROM collegestud WHERE id='" . $_GET['id'] . "'");
$row= mysqli_fetch_array($result);
?>
<form action="" method="POST" onsubmit="return confirm('Are you sure you want to save changes?');">
<div class= "container2">
<p style="font-weight: bold; font-size: 35px; text-align: center;">PSA</p>
<input type="hidden" name="ID" class="txtField" value="<?php echo $row['ID']; ?>">
<div class = "container3">
<center>
<input name="PSA" type = "file" accept = '.pdf'>
</center>
PROBLEM:
I just want to have a solution that instead it displays the filename of that file (text), it will show its filename in the table that is clickable to open its file in the another tab.

Answer 1

Yes, of course it possible. You should save also relative path to that PDF in database and then show link in UI part:
<!-- Start of table -->
<td>
Click to view
</td>
And your database table will have 1 additional field named path VARCHAR(256) NOT NULL with value e.g. students/some_name_of_file.pdf
Never store file content to database, it's not build to hold file contents
