No error shown when updating and deleting - php

Question

I have those codes that help to update and delete a row from a table:
html:
<table class="imagetable" cellpadding="3" cellspacing="1" width="400px" border="1">
<th>ID</th>
<th>Name</th>
<th>Informations</th>
<th>Actions</th>
<tr>
<td><input type="text" name="id" value="<?php echo $rows['id'] ?>"/></td>
<td><input type="text" name="med_name" value="<?php echo $rows['med_name'] ?>"/></td>
<td><input type="text" name="info" value="<?php echo $rows['info']?>"/></td>
<td>
<form action="update_del.php" method="post">
<input class="imgClass_update" type="submit" name="submit1" value="" />
<input class="imgClass_dell" type="submit" name="submit2" value=""/>
</form>
</td>
</tr>
<tr>
PHP:
<?php
require_once('../include/global.php');
$id=$_POST['id'];
if(isset($_POST['submit1']))
{
$name=$_POST['med_name'];
$info=$_POST['info'];
$sql = "UPDATE med SET med_name='$name',
info='$info'
WHERE id='$id'";
$result=mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if($result){
header("location:med.php");
}
else
{
header("location:update_false.php");
}
}
if(isset($_POST['submit2']))
{
$sql = "DELETE FROM med WHERE id='$id'";
$result=mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if(mysqli_affected_rows($con) == 1)
{
header("location:med.php");
}
else
{
header("location:update_false.php");
}
}
?>
Nothing is updated nor deleted. And no errors are shown. If someone could help me, I think the problem is too easy but can't see it where.

Answer 1

You are placing <form> tag at wrong place.
Therefore, your other elements: id, med_name and info are not children of form.
And they are not getting posted.
You should start <form> before table and end after table.
Corrected Code:
<form action="update_del.php" method="post">
<table class="imagetable" cellpadding="3" cellspacing="1" width="400px" border="1">
<tr>
<th>ID</th>
<th>Name</th>
<th>Informations</th>
<th>Actions</th>
</tr>
<tr>
<td><input type="text" name="id" value="<?php echo $rows['id'] ?>"/></td>
<td><input type="text" name="med_name" value="<?php echo $rows['med_name'] ?>"/></td>
<td><input type="text" name="info" value="<?php echo $rows['info']?>"/></td>
<td>
<input class="imgClass_update" type="submit" name="submit1" value="Update" />
<input class="imgClass_dell" type="submit" name="submit2" value="Delete"/>
</td>
</tr>
</table>
</form>

Answer 2

just do this -
<table class="imagetable" cellpadding="3" cellspacing="1" width="400px" border="1">
<form action="update_del.php" method="post">
<th>ID</th>
<th>Name</th>
<th>Informations</th>
<th>Actions</th>
<tr>
<td><input type="text" name="id" value="<?php echo $rows['id'] ?>"/></td>
<td><input type="text" name="med_name" value="<?php echo $rows['med_name'] ?>"/></td>
<td><input type="text" name="info" value="<?php echo $rows['info']?>"/></td>
<td>
<input class="imgClass_update" type="submit" name="submit1" value="" />
<input class="imgClass_dell" type="submit" name="submit2" value=""/>
</td>
</tr>
</form>
