Show checkbox is checked based on database value.

Adrian4263 · December 30, 2013

How could I declare checkbox, if checkbox is checked = 1 else = 0.And insert to mySQL.

<input type="checkbox" name="homepage" value="1" /> <-----this is my checkbox code. Only this i know.

somemore,if i already insert data to mySQL, how could i display checkbox is checked based on database, 1 = checked, 0 = unchecked.

I had try many code,but it won't work as well..Now i've no idea.

P/S:I'm using php code.

Please help.

Thanks.

Regards.

<input type="checkbox" name="homepage" value="1" <?php echo ($homepage == 1) ? 'checked="checked"' : ''; ?>/>

Where $homepage is the data retrieved from your database.

<input type="checkbox" name="homepage" value="1" <?php echo ($homepage == 1) ? 'checked="checked"' : ''; ?>/>
Where $homepage is the data retrieved from your database.

Thanks for your answer, i had tried your code, but the checkbox still show unchecked even my database value is 1

Here is a sample that works:



<?php 

$homepage = "0";

?>

<input type="checkbox" name="homepage" value="1" <?php echo ($homepage == 1) ? 'checked="checked"' : ''; ?>/>



<?php 

$homepage = "1";

?>

<input type="checkbox" name="homepage" value="1" <?php echo ($homepage == 1) ? 'checked="checked"' : ''; ?>/>

I suspect your database value is not in $homepage.

try:



<?php 

var_dump($homepage);

?>

To see if the value is actually there from the DB.

Thanks for your answer. I tried the code that you gave. If i add the code, it will add 2 more checkbox out, 1 is checked and the other one is unchecked. 1 of the checkbox always show checked, even the value is 0.

<?php 
var_dump($homepage);
?>

It come out value is "NULL"

I put this code at after the checkbox code.

What's wrong?

Firemankurt · December 30, 2013

Your database value is not in the variable.

How are you getting the value from Database?

How are you storing the value in Database?
