Im trying to get all of the checked values using array i already get all of the checked box and get the value but my problem is i want to pass to array all of value of checbox, 1 for check and 0 for uncheck. sorry for the english.
this is what i want to get:
array[0] = 1 //check
array[1] = 0 // uncheck
// and so on.
i have already tried a hidden box with same name of checkbox but it give me wrong data of array and i am sure its not the answer
<input type = "checkbox" name="checkbox[]" value="1">
$checkbox1 = ($_POST['checkbox'] <> 0) ? ($_POST['checkbox']) : (empty($_POST['checkbox'])) ?'0' : '';
output: 0
output of print_r($checkbox1) : 0
expected output : array[0]=> 1 --> check array[1] => 0 -> uncheck
When working with a PHP backend where you want to post an array of values (using the name="something[]" syntax) you need to create <input type="hidden"> and <input type="checkbox"> pairs that will refer to the exact same array index.
You do so by explicitly defining the index in the name attribute.
For example
<input type="hidden" name="checkbox[0]" value="0">
<input type="checkbox" name="checkbox[0]" value="1">
<input type="hidden" name="checkbox[1]" value="0">
<input type="checkbox" name="checkbox[1]" value="1">
<input type="hidden" name="checkbox[2]" value="0">
<input type="checkbox" name="checkbox[2]" value="1">
I believe this also works for ASP.NET-MVC backends. Not sure about others though.
If you're looping over records or a range, this is as simple as keeping an iteration index and using it in the name attributes
<?php for ($i = 0; $i < $range; $i++): ?>
<input type="hidden" name="checkbox[<?= $i ?>]" value="0">
<input type="checkbox" name="checkbox[<?= $i ?>]" value="1">
<?php endfor ?>

I have 1 form in with multiple checkboxes in it (each with the code):
<input type="checkbox" name="check_list" value="<? echo $row['Report ID'] ?>">
Where $row['Report ID'] is a primary key in a database -so each value is different.
How would I be able to tell which checkboxes have been checked? (Maybe multiple)
This is for an inbox system and I have a button below that I want (when clicked) to delete all messages (ids of: $row['Report ID']) which have the checkbox's checked.
Set the name in the form to check_list[] and you will be able to access all the checkboxes as an array($_POST['check_list'][]).
Here's a little sample as requested:
<form action="test.php" method="post">
<input type="checkbox" name="check_list[]" value="value 1">
<input type="checkbox" name="check_list[]" value="value 2">
<input type="checkbox" name="check_list[]" value="value 3">
<input type="checkbox" name="check_list[]" value="value 4">
<input type="checkbox" name="check_list[]" value="value 5">
<input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
foreach($_POST['check_list'] as $check) {
echo $check; //echoes the value set in the HTML form for each checked checkbox.
//so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
//in your case, it would echo whatever $row['Report ID'] is equivalent to.
}
}
?>
Edit To reflect what #Marc said in the comment below.
You can do a loop through all the posted values.
HTML:
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
PHP:
foreach($_POST['check_list'] as $item){
// query to delete where item = $item
}
you have to name your checkboxes accordingly:
<input type="checkbox" name="check_list[]" value="…" />
you can then access all checked checkboxes with
// loop over checked checkboxes
foreach($_POST['check_list'] as $checkbox) {
// do something
}
ps. make sure to properly escape your output (htmlspecialchars())
<input type="checkbox" name="check_list[<? echo $row['Report ID'] ?>]" value="<? echo $row['Report ID'] ?>">
And after the post, you can loop through them:
if(!empty($_POST['check_list'])){
foreach($_POST['check_list'] as $report_id){
echo "$report_id was checked! ";
}
}
Or get a certain value posted from previous page:
if(isset($_POST['check_list'][$report_id])){
echo $report_id . " was checked!<br/>";
}
It's pretty simple. Pay attention and you'll get it right away! :)
You will create a html array, which will be then sent to php array.
Your html code will look like this:
<input type="checkbox" name="check_list[1]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[2]" alt="Checkbox" value="checked">
<input type="checkbox" name="check_list[3]" alt="Checkbox" value="checked">
Where [1] [2] [3] are the IDs of your messages, meaning that you will echo your $row['Report ID'] in their place.
Then, when you submit the form, your PHP array will look like this:
print_r($check_list)
[1] => checked
[3] => checked
Depending on which were checked and which were not.
I'm sure you can continue from this point forward.
I have this code on my form for the checkboxs:
<input type="hidden" name="option_desc[]" value="option 1"/>
<label><input type="checkbox" name="option_price[]" value="10" class="option_checkbox"/>option 1</label>
<input type="hidden" name="option_desc[]" value="option 2"/>
<label><input type="checkbox" name="option_price[]" value="20" class="option_checkbox"/>option 2</label>
<input type="hidden" name="option_desc[]" value="option 3"/>
<label><input type="checkbox" name="option_price[]" value="30" class="option_checkbox"/>option 3</label>
I'm trying to get the POST values of the checkbox that the user checked (for example, if he checked the second checkbox: "option 2" + "20") and store them:
$articleDetails['options'] = array();
$count = 0;
if(is_array($_POST['option_price'])){
foreach($_POST['option_price'] as $key => $value){
if($value){
$articleDetails['options'][$count]['option_price'] = $_POST['option_price'][$key];
$articleDetails['options'][$count]['option_desc'] = $_POST['option_desc'][$key];
$count++;
}
}
}
When the user check one of the checkbox, the appropriate 'option_price' is stored correctly, but the 'option_desc' is not the one that belongs to the CHECKED checkbox (for example: when the second checkbox is checked the values that I get are "20" (GOOD) and "option 1" (NOT GOOD).
What I'm doing wrong?
Thanks.
The problem you are having is that if checkboxes are not checked, the data won't get POSTed while your hidden inputs will always be posted. Frankly, I don't see what value your hidden inputs give you here. They tell you absolutely nothing about the posted data that you don't already know about on the server.
You should simply use a defined index in your array notation for the checkbox field, like this:
<input type="checkbox" name="option_price[1]" value="10" class="option_checkbox"/>option 1</label>
<input type="checkbox" name="option_price[2]" value="20" class="option_checkbox"/>option 2</label>
<input type="checkbox" name="option_price[3]" value="30" class="option_checkbox"/>option 3</label>
Note: I didn't use zero-indexed array here as I figured you might want to directly relate $_POST['option_price'][1] to "option 1".
To add some examples related to the discussion in comments below. Say for example you had some option_price checkboxes you want to output, and they come from some dynamic source. Your code to to generate the checkboxes might look something like this:
$price_options = array(
array(
'description' => 'eBook',
'value' => 10
),
array(
'description' => 'articles',
'value' => 20
),
// and so on
);
$count = count($price_options)
for($i = 1; $i<= $count; $i++) {
?>
<input type="checkbox" name="option_price[<?php echo $i; ?>]" value="<?php echo $price_options[$i]['value']; ?>" class="option_checkbox"/><?php echo $price_options[$i]['description']; ?></label>
<?php
} // end for
When POSTing you know that every $_POST['option_price'][x] would correspond to the item at $price_options[x].
You could simply iterate of $_POST['option_price'] to see which items are selected like this:
if(!empty($_POST['option_price']) {
foreach ($_POST['option_price'] as $index => $value) {
// verify value hasn't been tampered with
if ((int) $value === $price_options[$index]['value']) {
// set description
$description = $price_options[$index]['description'];
var_dump($description, $value);
}
}
}
I would suggest give names to input like
<input type=hidden name="option[1][desc]"/>
<input type=hidden name="option[1][price]"/>
Then I think it would be easy to run a forreach as well.
I am writing some code for a module for Zen Cart. $stores_id is an array containing 3 values:
$stores_id[0]="1";
$stores_id[1]="2";
$stores_id[2]="3";
With the following code I am trying to echo a hidden input field, filled with data from the array
for ($i=0, $n=sizeof($stores_id); $i<$n; $i++)
{
echo zen_draw_hidden_field('stores_id['. $stores_id[$i]['stores_id'] .']', htmlspecialchars(stripslashes($stores_id[$stores_id[$i]['stores_id']]), ENT_COMPAT, CHARSET, TRUE));
}
the echoed result is:
<input type="hidden" value="2" name="stores_id[1]">
<input type="hidden" value="3" name="stores_id[2]">
<input type="hidden" name="stores_id[3]">
while I expected it to be:
<input type="hidden" value="1" name="stores_id[1]">
<input type="hidden" value="2" name="stores_id[2]">
<input type="hidden" value="3" name="stores_id[3]">
Can anyone tell me what I am doing wrong?
It looks like you are nesting your 2nd parameter 1 depth too far -
$stores_id[$stores_id[$i]['stores_id']]
So when $i == 0, you are getting $stores_id[1], which is 2, instead of $stores_id[0] which is 1. And when you get to $i == 2 you have $stores_id[3] which is not in the array.
So either remove the outer array -
htmlspecialchars(stripslashes($stores_id[$i]['stores_id'])
or subtract 1 from the inner array returned value
htmlspecialchars(stripslashes($stores_id[$stores_id[$i]['stores_id']-1])
This is the HTML:
<input type="text" name="shortcut[]" value="a"/> do <input type="text" name="ses[]" value="1" disabled/><br>
<input type="text" name="shortcut[]" value="b"/> do <input type="text" name="ses[]" value="2" disabled/><br>
<input type="text" name="shortcut[]" value="c"/> do <input type="text" name="ses[]" value="3" disabled/><br>
How do I pass the values to PHP but connect the indexes of both arrays?
i.e. put in database value 1 where something = a,
put in database value 2 where something = b
and so on ...
The indexes are connected automatically, since they're numeric arrays.
$nvals = count($_REQUEST['shortcut']);
for ($i = 0; $i < $nvals; $i++) {
// do something with $_REQUEST['shortcut'][$i] and $_REQUEST['ses'][$i]
}
Combined array: array_map(null,$_POST['shortcut'],$_POST['ses']);
But you could of course could foreach over one of the 2, and fetch the other by key.
Note that if you have elements which may or may not be sent (checkboxes for instance), the only way to keep groups together is to assign them a number beforehand (name=sess[1], name=sess[2], etc.)
You can specify shortcut value as the key and the ses value as the value attribute:
<input type="text" name="input[a]" value="1" />
<input type="text" name="input[b]" value="2" />
<input type="text" name="input[c]" value="3" />
On the server-side you could use a foreach loop to iterate over the array:
foreach ($_POST['input'] as $shortcut => $ses) {
// process $shortcut and $ses
}
I have a form with many checkboxes.
ex.
...
<input name="dodatkowe[]" type="checkbox" value="1" />
<input name="dodatkowe[]" type="checkbox" value="1" />
<input name="dodatkowe[]" type="checkbox" value="1" />
...
I want to have all the checkboxes in the array. Array 'dodatkowe'.
When i checked all checkboxes have:
Array ( [0] => 1 [1] => 1 [2] => 1 )
but when i checked example only second I have:
Array ( [0] => 1 )
I need that, when i check example second checkbox:
Array ( [0] => 0 [1] => 1 [2] => 0)
give them indexes so you can reference them specifically...
...
<input name="dodatkowe[1]" type="checkbox" value="1" />
<input name="dodatkowe[2]" type="checkbox" value="1" />
<input name="dodatkowe[3]" type="checkbox" value="1" />
...
Not sure why you feel you need to see the unchecked values, this can be assumed to be the inverse of the checked values.... Any attempt to do this is a hack, and is unnecessary.
If a checkbox isn't checked it won't include it's value into the parameters but the first step would be to give the checkboxes a unique id:
<input name="dodatkowe[0]" type="checkbox" value="1" />
<input name="dodatkowe[1]" type="checkbox" value="1" />
<input name="dodatkowe[2]" type="checkbox" value="1" />
Then you can use PHP to check is the value is there:
$maxfields = 3;
$selectboxes = $_REQUEST['dodatkowe'];
for($i = 0; $i < $maxfields; $i++)
if(!isset($selectboxes[$i])) $selectboxes[$i] = 0;
This will set all non existent fields to 0 and $selectboxes should contain the result you are looking for.
