Checkbox with $_POST

[NuMan]

Hello, Im trying to insert some information into my database from checkboxes, but my $_POST does not work.

 

This is what I am using:

 

$checkbox = $_POST['checkbox[]'];

 

Is this the correct way of doing this? Thanks in advance.

Hi,

 

This is a copy from my site that I use, but pretty much looks like yours.

 

<input type="checkbox" name="confirm">

...
blah blah
...

$checkbox = $_POST["confirm"]

[redarrow]

Can i see the form please, it seems your using arrays are you..

 

example if it arrays

 

<?php  


foreach($_POST'array_name'] as $result){

echo $result;

}
?>

 

or

 

another array way.

 

<?php

$result=implode('  ',$_POST['array_name']);

echo $result;

?>

This is my input:

<input type=checkbox name=chekbox[] value={$checkboxinfo[i].id}>

which works pretty good to show the information. I tried what you said but it didn't work.

Could you explain a little more please? I gave more information in this post about my problem.

If you have named you checkbox as checkbox[]

 

Then use

$_POST['checkbox'][0] - first checbox

$_POST['checkbox'][1] - secound checbox

$_POST['checkbox'][2] - third checbox

etc.

 

You can easily loop through your checkboxes too,

foreac($_POST['checkbox'] as $cbox)
{
    echo $chox;
}

Oh, is there anyway i can do

$checkbox = the loop? of it? sorry im not very good i this

[NuMan]

by the way, each one of the checkboxes represent a number so im wondering if there's anyway to count up to the number of the one thats checked and record that number. as a variable?

Post an example of your form here. Not quite understanding you fully from what you said above.

<input type=checkbox name=chlist[] value={$chinfo.id}>{$chinfo.ch}

 

Its part of a script. It shows the channels that are in a database.

[wildteen88]

When the form is submitted what do you want to do with the checkboxes?

[NuMan]

i just want it to be recorded into the databased.

[wildteen88]

Then use

// loop through the checkboxes
foreach($_POST['checkbox'] as $values)
{
    // inset each one into database
    $sql = "INSERT INTO your_table SET your_field='$value'";
    mysql_query($sql) or die('Query Error: ' .$sql.'<br />'.mysql_error());
}

}

 

Hello, I am trying a more simpler way now without databases. This is what i have:

 

if($_POST['Reggaeton']) {
$checkbox = 1;
} elseif($_POST['Merengue']) {
$checkbox = 2; 
} elseif($_POST['Dominican Hip-Hop']) {
$checkbox = 3; 
} elseif($_POST['Rap']) {
$checkbox = 4; 
} elseif($_POST['Rock']) {
$checkbox = 5; 
}

 

And this is my form:

<input type="checkbox" name="Reggaeton" value="Reggaeton">Reggaeton<br>
	<input type="checkbox" name="Merengue" value="Merengue">Merengue<br>
	<input type="checkbox" name="Dominican Hip-Hop" value="Dominican Hip-Hop">Dominican Hip-Hop<br>
	<input type="checkbox" name="Rap" value="Rap">Rap<br>
	<input type="checkbox" name="Rock" value="Rock">Rock<br>

 

It is still not working. Any help.

The code you posted does not make sense. If you're user selected Hip-Hop and Rap only this part of your if statement will execute

if($_POST['Reggaeton']) {

$checkbox = 1;

} elseif($_POST['Merengue']) {

$checkbox = 2;

} elseif($_POST['Dominican Hip-Hop']) {

$checkbox = 3;

} elseif($_POST['Rap']) {

$checkbox = 4;

} elseif($_POST['Rock']) {

$checkbox = 5;

}

Yes, thats what i want it to do. If they select hip hop i want the value of $checkbox to be 3 or if they select rap i want it to be 4. Oh yeah and they can only select 1 genre i have a check for it. Maybe ill change it to radios.

So you want one selection to be made. if so you should use radio buttons instead rather than checkboxes.

<input type="radio" name="genre" value="Reggaeton">Reggaeton<br>
<input type="radio" name="genre" value="Merengue">Merengue<br>
<input type="radio" name="genre" value="Dominican Hip-Hop">Dominican Hip-Hop<br>
<input type="radio" name="genre" value="Rap">Rap<br>
<input type="radrio" name="genre" value="Rock">Rock<br>

 

Now use $_POST['genre'] to get the selection.

Now use $_POST['genre'] to get the selection.

 

tried this with this and didn't work.:

if($_POST['genre'] == Reggaeton) {
$radio = 1;
} elseif($_POST['genre'] == Merengue) {
$radio = 2; 
} elseif($_POST['genre'] == DominicanHipHop) {
$radio = 3; 
} elseif($_POST['genre'] == Rap) {
$radio = 4; 
} elseif($_POST['genre'] == Rock) {
$radio = 5; 
}

Im sorry for bothering so much.
