Adding delete button into the table - php

Question

I have to add delete button into each section of the table.
<?php
$link = mysqli_connect("localhost", "root", "", "demo");
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$name = mysqli_real_escape_string($link, $_POST['name']);
$email = mysqli_real_escape_string($link, $_POST['email']);
$contact = mysqli_real_escape_string($link, $_POST['contact']);
$sql = "INSERT INTO persons (name, email, contact) VALUES ('$name', '$email', '$contact')";
if(mysqli_query($link, $sql)){
echo "<h2>Records added successfully.The new updated records are...</h2><br>";
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
$selectData = "select * from persons";
$res = mysqli_query($link, $selectData);
?>
<table border="2">
<tr>
<th>id</th>
<th>Name</th>
<th>Email</th>
<th>Contact</th>
</tr>
</table>
<?php
if(mysqli_num_rows($res)>0){
while($row = mysqli_fetch_assoc($res)){
?>
<tr><td><?php echo $row['id'];?></td>
<td><?php echo $row['name'];?></td>
<td><?php echo $row['email'];?></td>
<td><?php echo $row['contact'];?></td></tr>
<?php
}
}
?>

Answer 1

<tr><th>id</th>
<th>Name</th>
<th>Email</th>
<th>Contact</th>
<th>Delete</th>
</tr>
<?php
if(mysqli_num_rows($res)>0){
while($row = mysqli_fetch_assoc($res)){
?>
<tr><td><?php echo $row['id'];?></td>
<td><?php echo $row['name'];?></td>
<td><?php echo $row['email'];?></td>
<td><?php echo $row['contact'];?></td></tr>
<td><a onClick="delTopicContentRow('<?php echo $row['id'] ?>')"><img src="../admin_assets/images/delete.png"></a></td>
<?php
}
}
The delete javascript function
function delTopicContentRow(topic_content_id)
{
var confirm_delete = confirm("Do you want to delete topic content ?");
if (confirm_delete === true)
{
$(".deleteall"+topic_content_id).addClass("deletealloncomplete");
$.ajax({
type:'POST',
url:'delRow.php',
data:{topic_content_id:topic_content_id},
success:function(data)
{
if(data == 1)
{
$(".deletealloncomplete").fadeOut("slow");
setTimeout(function(){
window.location.reload(1);
}, 2000);
}
else
{
alert("Try again.!");
}
}
});
}
}

Answer 3

<tr><th>id</th>
<th>Name</th>
<th>Email</th>
<th>Contact</th>
<th>Delete</th>
</tr>
<?php
if(mysqli_num_rows($res)>0){
while($row = mysqli_fetch_assoc($res)){
?>
<tr><td><?php echo $row['id'];?></td>
<td><?php echo $row['name'];?></td>
<td><?php echo $row['email'];?></td>
<td><?php echo $row['contact'];?></td></tr>
<td>Delete item
</td>
<?php
}
}
//This last statement passes the id of the function to delete
function delete(){
if(isset($_GET['delete'])){
$id=$_GET['delete'];
$sql="DELETE FROM `trial` WHERE `id` ='$id'";
$stmt=$this->conn->prepare($sql);
$stmt->execute();
}
}
?>
