Example

In this example, we implement storing multiple checkbox values in a database in PHP. There are certain steps we need to follow as explained below.

Step 1

Create an HTML form, test_post.php, with multiple checkboxes as shown below.

<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
<div style="width:200px;border-radius:6px;margin:0px auto">
<table border="1">
<tr>
<td colspan="2">Select Technolgy:</td>
</tr>
<tr>
<td>PHP</td>
<td><input type="checkbox" name="techno[]" value="PHP"></td>
</tr>
<tr>
<td>.Net</td>
<td><input type="checkbox" name="techno[]" value=".Net"></td>
</tr>
<tr>
<td>Java</td>
<td><input type="checkbox" name="techno[]" value="Java"></td>
</tr>
<tr>
<td>Javascript</td>
<td><input type="checkbox" name="techno[]" value="javascript"></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="submit" name="sub"></td>
</tr>
</table>
</div>
</form>
<?php
if(isset($_POST['sub']))
{
$host="localhost";//host name
$username="root"; //database username
$word="";//database word
$db_name="sub_db";//database name
$tbl_name="request_quote"; //table name
$con=mysqli_connect("$host", "$username", "$word","$db_name")or die("cannot connect");//connection string
$checkbox1=$_POST['techno'];
$chk="";
foreach($checkbox1 as $chk1)
{
$chk .= $chk1.",";
}
$in_ch=mysqli_query($con,"insert into request_quote(technology) values ('$chk')");
if($in_ch==1)
{
echo'<script>alert("Inserted Successfully")</script>';
}
else
{
echo'<script>alert("Failed To Insert")</script>';
}
}
?>
</body>
</html>
