I'm getting database from database and each row has a id and im showing it like this in html
<td><input type="checkbox" value"1">test1</td></tr>
<td><input type="checkbox" value"2">test2</td></tr>
and so on...
now lets say that user checked ten check boxes out of 15 and then clicked submit .
how to get values of those boxes in php???
Your checkboxes need to have a name & a value attribute:
<input type='checkbox' name='test1' value='1'> Test1
<input type='checkbox' name='test2' value='1'> Test2
then when that is posted you can access the values in PHP via $_POST:
$test1 = $_POST['test1']
$test2 = $_POST['test2']
Keep in mind that the values will only be returned if the box is checked, so most likely instead of the above PHP, you're more than likely just going to want to check if the value exists.
give the checkboxes names:
<td><input type="checkbox" value"2" name='test'>test2</td></tr>
Than in php just read the request
$test = $_REQUEST['test']
if the OP doesn't have these checkboxes inside of a , any amount of PHP code will make absolutely no difference (FROM Blender)
they will be in either the $_GET or the $_POST array
Try this way..
<form action="#" method="post">
<input type="checkbox" name="check_list[]" value="1"><label>Test 1</label><br/>
<input type="checkbox" name="check_list[]" value="2"><label>Test 1</label><br/>
<input type="checkbox" name="check_list[]" value="3"><label>Test 3</label><br/>
<input type="submit" name="submit" value="Submit"/>
</form>
<?php
if(isset($_POST['submit'])){//to run PHP script on submit
if(!empty($_POST['check_list'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['check_list'] as $selected){
echo $selected."</br>";
}
}
}
?>

I have a form using the GET method consisting of checkboxes.
This form is sending data to another page that is receiving the GET info and using it to pull info from a json api. I need to have it send the name once with all values combined into one string like this: example.com/color=RedGreenBlue
I am able to get all values combined and echoed onto the page but because they are in a foreach loop I am not able to pass them in the form. I tried below using the hidden field to pass them with no luck.
This is the method I've seen suggested but does not work for me:
<form action="" method="get">
Red<input type="checkbox" name="color[]" value="Red">
Green<input type="checkbox" name="color[]" value="Green">
Blue<input type="checkbox" name="color[]" value="blue">
<input type="submit" value="submit">
<?php
$name = $_GET['color'];
if (isset($_GET['color'])) {
foreach ($name as $color){
echo $color;
}
}
?>
<input type="hidden" name="MajorArea" value="<?php echo $color; ?>" />
</form>
Is there a way to assign one name to a group of checkboxes? Is there a way to pull the foreach loop data and use it outside a loop? Am I overlooking a way that is much easier than this?
Thanks for any advice!
I'll go out on a limb here and delete if it isn't what you're after. $_GET['color'] will be an array or it will be empty. You could also use isset:
<form action="" method="get">
Red<input type="checkbox" name="color[]" value="Red">
Green<input type="checkbox" name="color[]" value="Green">
Blue<input type="checkbox" name="color[]" value="blue">
<input type="submit" value="submit">
</form>
<?php
if (!empty($_GET['color'])) {
echo implode($_GET['color']);
}
?>
This question will show what a newbie I am. The situation is this. It's a photo contest.
People upload a photo and to the right on the same line is a checkbox.
Voters check the box if they like the photo. They can select up to, say, 5 photos.
Keeping it simple, my problem isn't with MySQL, but with the form. Each row has a checkbox, which is a form. The SUBMIT button is the problem. The only way I can figure out to have submit work is by putting a submit button with each checkbox. Of course, that's ridiculous. What I want is to read all the checked boxes and have ONE submit button when the voter is finished. Spent hours on this and can't see how to have the SUBMIT by itself that the voter can click and have all the checked values inserted into the database a one time.
Any notions? I know this sound very primitive, but just getting into this.
Thanks ahead of time for any help
You can enclose all the checkboxes in a single html form tag and have the submit button inside it. It'll automatically submit data in all checkboxes
Or
You can use javascript/jQuery to run through all the checkboxes. And submit the form.
Well, there are all sorts of javascript ways to go out and grab the data you want and submit it, but let's keep it simple.
[voteform.html]
<form action="process_script.php">
<img src="image1"><input type="checkbox" name="vote_for_image[]" value="1">
<img src="image2"><input type="checkbox" name="vote_for_image[]" value="2">
<input type="submit">
</form>
... then ... (please note the [RETURN ERROR...] and [DATABASE...] blocks are just place holders for you to fill in code)
[process_script.php]
<?
if (count($_GET['vote_for_image'] > 5) {
[RETURN ERROR 'Please select no more than 5 images to vote for']
}
else {
foreach ($_GET['vote_for_image'] as $index => $image_id) {
[DATABASE INSERT OR UPDATE FOR $image_id]
}
}
?>
Set the checkbox[] as name attribute for each checkbox and on submission you can address the valiues as arrays
<body>
<form action="checkbox.php" method="post">
<input type="checkbox" name="checkbox[]" value="a">
<input type="checkbox" name="checkbox[]" value="b">
<input type="checkbox" name="checkbox[]" value="c">
<input type="checkbox" name="checkbox[]" value="d">
<input type="submit" name="Submit" value="Submit">
</form>
<?php
if(isset($_POST['Submit']))
{
echo $_POST['checkbox'];
}
?>
</body>
the above will give you
Array (
[0] => a
[1]=>b
[2] => c
[3]=>d
)
Try this code
//HTML
<form method='post'>
<input type='checkbox' name='photo[]' value='1' />
<img src='test1.jpg' />
<input type='checkbox' name='photo[]' value='2'/>
<img src='test2.jpg' />
<input type='submit' value="Submit" name="submit" />
</form>
//PHP
if(isset($_POST['submit']))
{
if(isset($_POST['photo']))
{
if(count($_POST['photo']) > 5)
{
// Display error msg
}
else
{
// Contains all ids voted on
$img_ids=explode(',',$_POST['photo']);
// insert or update DB for the image ids
}
}
}
Is it possible to submit forms with input checkboxes, each containing the same name, to a PHP script?
Is it possible to loop through the names to get all the values?
I am building a message system, and users can add/remove recipients dynamically. When they do, a hidden checkbox is generated in the form containing the value, yet I'm not sure what to do with the name. On the php end, on top of the recipients a subject and a message are submitted, and the script needs to loop through each name and perform various SQL tasks. I know there are much better ways of doing this, and feel free to suggest, but I'd really like to know if it can get done this way. Comment if you need to see code, but I warn you, it's really confusing.
<input type="checkbox" name="samename[]">
// on the post/get:
foreach( $_POST['samename'] as $eachId ){
// do whatever you want. build the where in a query, ' set = '.$eachId
}
Yes you can, use the same name with [] after it, it will cause all of the values to be stored in an array on PHP.
<input type=checkbox value=1 name=check[]>
<input type=checkbox value=2 name=check[]>
<input type=checkbox value=3 name=check[]>
<input type=checkbox value=4 name=check[]>
<input type=checkbox value=5 name=check[]>
Yes you can, array of post, look at this example:
<?php
print_r($_POST);
?>
<form action="form.php" method="POST">
<input type="checkbox" name="vehicle[]" value="Bike" /> I have a bike<br />
<input type="checkbox" name="vehicle[]" value="Car" /> I have a car
<input type="submit" value="Submit" />
</form>
Notice how vehicle has the square brackets?
I'm trying to get the ID's from a load of checkboxes that are in rows that are printed out on a page using a while statement. Each row from the database has a checkbox next to it with the ID in the checkbox value.
Basically I want to do a update query on the checkbox-selected rows, using the ID.
The code for the checkboxes that I have used is:
<input type="checkbox" name="check_list[]" value="<? echo $rows['id']; ?>">
Then when the code for the submit is:
<?
if(!empty($_POST['check_list'])){
foreach($_POST['check_list'] as $id){
echo "$id was checked! ";
}
}
?>
Just wanted to echo out the results to test that it works before putting it into a query. Trouble is...nothing happens. I just get a blank screen. No error or anything. Surely it should work, it looks right but I don't understand why it doesnt work.
Any help is most appreciated! :)
Tested below code with one test.php file
<?php
if(!empty($_POST['check_list']))
{
foreach($_POST['check_list'] as $id){
echo "<br>$id was checked! ";
}
}
?>
<form method="post" name="frm">
<input type="checkbox" name="check_list[]" value="1"> 1
<input type="checkbox" name="check_list[]" value="2"> 2
<input type="checkbox" name="check_list[]" value="3"> 3
<input type="checkbox" name="check_list[]" value="4"> 4
<input type="submit" name="submit" />
</form>
please check if you are getting $rows['id'] properly. Things should work fine otherwise.
Thanks.
Hi I have a form like that
<form method=post action="control.php">
<input name="cat[]" type="checkbox" value="blabla" checked>blabla
<input name="cat[]" type="checkbox" value="bleble" checked>bleble
.
.
.
<input name="send" type="submit" id="send" value="send">
</form>
in control.php, I want to get unchecked box when I use $_POST[cat]. How can I do that? thanks for help...
Checkbox groups (cat[]) can easily be generated from an array, using a foreach.
$cat=array(
'blabla' => 'blabla',
'bleble' => 'bleble',
...
);
<? foreach ($cat as $k=>$v) : ?>
<input name="cat[]" type="checkbox" value="<?=$k?>" checked /><?=$v?>
<? endforeach; ?>
If you have an array with all the possible checkboxes, it is very easy to compare it with the POSTed array of selected checkboxes, and find out which ones are missing.
You can use array_diff for that:
$unchecked=array_diff(array_keys($cat), $_POST['cat']);
You can't get the unchecked box, you can only get the checked ones.
If you need the unchecked boxes, you'll have to look at the checked boxes and figure out which ones were not checked.
