I've got a lot of radio boxes on a single page within my website.
I know it is possible to submit all of the options as an array that can be directly manipulated by PHP.
<input type="radio" name="SOMETHING_HERE" value="1" />
There are several radio groups and I'd like all of them to submit to one array.
All I'd like to know is the syntax which has to be used in the name="".
Use like this
<input type="radio" name="optionname[]" value="1" />
<input type="radio" name="optionname[]" value="2" />
.
.
You can have your form in either of the following ways.
<input type="radio" name="name[]" value="1" />
<input type="radio" name="name[]" value="2" />
Or
<input type="radio" name="question['question1']" value="1" />
<input type="radio" name="question['question2']" value="2" />
There by you setting the array definition yourself. Hope this answers your query.
HTML looks like this:
<input type="radio" name="name[]" value="1" />
<input type="radio" name="name[]" value="2" />
PHP accesses it like this:
<?php
$_POST['name'] = array('1','2');
Some things to note:
Order in array as compared to as it exists in HTML is not guaranteed

I am working on a custom survey that is dynamically populated with database information and needs to be saved as an array. I can make everything work as it should except I would like to use a star rating system for many of the answers and it seems radio buttons won't work like this:
<input type="radio" name="surveyRating[]" value="1" />
<input type="radio" name="surveyRating[]" value="2" />
<input type="radio" name="surveyRating[]" value="3" />
<input type="radio" name="surveyRating[]" value="4" />
<input type="radio" name="surveyRating[]" value="5" />
Because there are multiple instances of this same code. This will be saved into an array so surveyRating will be used over and over again. If I click a radio button in one group, it changes to a radio in another group.
I have read I can possibly do this with checkboxes instead. Is that the best alternative? Or is there another option I should be looking at? I want the final product to be star ratings 1-5. Not sure if I can do that with checkboxes.
EDIT
Ok so using name="surveyRating[1]" is helping as far as the radio buttons not conflicting on the client side. However, it is not saving correctly the way I have my php set up now. Here is how it is saved currently. What do I need to change to make the [1] work appropriately. Currently it is only saving the last iteration.
$new = array();
$ratings = $_POST['surveyRating'];
$count = count( $ratings );
for ( $i = 0; $i < $count; $i++ ) {
if ( $ratings[$i] != '' ) {
$new[$i]['surveyRating'] = stripslashes( strip_tags( $ratings[$i] ) );
}
}
EDIT 2
So to demonstrate how I accomplished this using the answer below, I had to add [0] as the first iteration in the loop. I was using $items = 0; $items++ to dynamically add a number to each loop.
To make it start at 0, I set $items = -1 that way the first iteration is 0 instead of 1. Hope that makes sense.
Yep, it does because you have the name with []. That's for array. Remove it and you will get it without array:
<input type="radio" name="surveyRating" value="1" />
<input type="radio" name="surveyRating" value="2" />
<input type="radio" name="surveyRating" value="3" />
<input type="radio" name="surveyRating" value="4" />
<input type="radio" name="surveyRating" value="5" />
For radio buttons with several groups, you have to do something like this:
<!-- Group 1 -->
<input type="radio" name="surveyRating[1]" value="1" />
<input type="radio" name="surveyRating[1]" value="2" />
<input type="radio" name="surveyRating[1]" value="3" />
<input type="radio" name="surveyRating[1]" value="4" />
<input type="radio" name="surveyRating[1]" value="5" />
<!-- Group 2 -->
<input type="radio" name="surveyRating[2]" value="1" />
<input type="radio" name="surveyRating[2]" value="2" />
<input type="radio" name="surveyRating[2]" value="3" />
<input type="radio" name="surveyRating[2]" value="4" />
<input type="radio" name="surveyRating[2]" value="5" />
Trying to create a search function using multiple checkboxes, but seem to be only finding information related to $_POST requests.
<input type="checkbox" name="fruit" value="1">
<input type="checkbox" name="fruit" value="2">
<input type="checkbox" name="fruit" value="3">
<input type="checkbox" name="fruit" value="4">
<input type="checkbox" name="fruit" value="5">
What is the best way to get the query to look like this
search?fruit=1,2,3,4
Is there a way to do this non ajax?
Just to clarify...
Each value represents a different fruit.
Originally I did this
search?apple=1&orange=1
As I added more checkboxes, the query seemed inefficient.
I know that I can add the checkboxes into the array using the $_POST method
<input type="checkbox" name="fruit[]" value="1">
<input type="checkbox" name="fruit[]" value="2">
As a few have suggested using this technique for a $_GET query would look something like this
search?fruit[]=1&fruit[]=2&fruit[]=5
So the question is really how to clean it up (comma seperated)
NOTE: As others have pointed out, it isn't necessary to pass a single parameter with a comma-separated value to end up with an array or a comma-separated value on the server. Frameworks like PHP can handle this with no JavaScript required. You can simply give each checkbox the same "name" attribute. That will cause multiple parameters with the same name to be passed to the server, which is just fine. In fact, it is the same result you would get if you used a <select multiptle="multiple"> element.
In PHP, if you use a name with square brackets at the end, like fruit[], you can then get an array on the server with:
$_GET['fruit']
And if you want a comma-separated value on the server, you can use:
implode(',', $_GET['fruit'])
But if you really want a single parameter with a comma-separated value, here is how you can do it:
You can use a form with a hidden input. Set the form's "method" to "get" and the hidden input's "name" to "fruit". Then add an event handler that sets the value of the hidden input to the comma-separated string when the form is submitted.
HTML:
<form id="fruitForm" action="search" method="get">
<input type="hidden" name="fruit" />
<label><input type="checkbox" value="1" />apple</label><br />
<label><input type="checkbox" value="2" />banana</label><br />
<label><input type="checkbox" value="3" />orange</label><br />
<label><input type="checkbox" value="4" />pineapple</label><br />
<label><input type="checkbox" value="5" />grapefruit</label><br />
<button type="submit">submit</button>
</form>
JQuery:
$('#fruitForm').submit(function() {
var fruits = $('#fruitForm').find('input:checkbox:checked').map(function() {
return $(this).val();
}).get().join(',');
$('#fruitForm').find('input[name=fruit]').val(fruits);
});
Note: The checkbox elements do not have "name" attributes, so they do not get included in the form submission.
jsfiddle
Use fruit[] as the input name
<input type="checkbox" name="fruit[]" value="1">
<input type="checkbox" name="fruit[]" value="2">
<input type="checkbox" name="fruit[]" value="3">
<input type="checkbox" name="fruit[]" value="4">
<input type="checkbox" name="fruit[]" value="5">
You will get the following:
echo "<pre>", print_r($_GET["fruit"], true);
Output
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
Try this, Use checkbox name as fruit[]. In php get the fruit array and converted as string using implode()
<?php
echo $fruits = implode(",",$_GET['fruit']); //1,2,3,4,5
?>
<form>
<input type="checkbox" name="fruit[]" value="1">
<input type="checkbox" name="fruit[]" value="2">
<input type="checkbox" name="fruit[]" value="3">
<input type="checkbox" name="fruit[]" value="4">
<input type="checkbox" name="fruit[]" value="5">
<input type="submit">
</form>
I need a form in which the checkboxes would open different pages based on their selection when the form is submitted.
So, say I have this simple form:
<form action="" method="post">
<input value="1" type="checkbox" name="sign" />
<input value="2" type="checkbox" name="sign" />
<input value="3" type="checkbox" name="sign" />
<input value="4" type="checkbox" name="sign" />
<input value="5" type="checkbox" name="sign" />
<input type="submit" />
</form>
When an user checks value 1 and submits, he will be redirected to page A. If a user checks 1 and 4 he will be redirected to a different page (page F, for instance). If a user checks 2, 3 and 4 he will be redirected to page R, and so on... There would be 25 different combinations, and therefore, 25 different page results for this form when an user submits it.
In other words, when the form is submitted somehow the system would read which checkboxes were checked and associate each possible combination with a different URL.
Can it be done? If so, how? Anyone ever made something similar? I've searched a long time for solutions, but found only slightly similar ones, not exactly what I need, so any help would be appreciated.
HTML:
<form action="" method="post">
<input value="1" type="checkbox" name="sign[1]" />
<input value="2" type="checkbox" name="sign[2]" />
<input value="3" type="checkbox" name="sign[3]" />
<input value="4" type="checkbox" name="sign[4]" />
<input value="5" type="checkbox" name="sign[5]" />
<input type="submit" />
</form>
PHP:
if (isset($_POST['sign'][1]))
header("Location: a.php");
elseif(isset($_POST['sign'][2]) AND isset($_POST['sign'][3]))
header("Location: b.php");
This can be done in a couple of ways. One is that you can use javascript to intercept the form submission, change the value of the form "action", and then execute the submit.
A second approach might be to just send all this data to a single script and based on the selected values perform a redirect to the intended page.
From should look like:
<form action="" method="post">
<input value="1" type="checkbox" name="sign[]" />
<input value="2" type="checkbox" name="sign[]" />
<input value="3" type="checkbox" name="sign[]" />
<input value="4" type="checkbox" name="sign[]" />
<input value="5" type="checkbox" name="sign[]" />
<input type="submit" />
</form>
And the post like:
if(!empty($_POST['sign'])) {
if(in_array(1, $_POST['sign'])) {
// if just 1, go to page
} elseif(in_array(1, $_POST['sign']) && in_array(4, $_POST['sign'])) {
// if 1 and 4, go to page
}
}
You can just consider each of the inputs as a bit. So, you will always have 5 bits to consider.
Then define an associative array of 25 entries corresponding to each of the possible values:
00001
00010
...
var links = {
"00001" : "www.google.com",
];
Then, when you submit the form, just set the target attribute of the form based on the value.
If I were you and I had no choice than following this idea, I would use something like that in jQuery (assuming your post vars are treated in the page you want to reach):
<form action="" method="post" id="myForm">
<input value="1" type="checkbox" name="sign[]" />
<input value="2" type="checkbox" name="sign[]" />
<input value="3" type="checkbox" name="sign[]" />
<input value="4" type="checkbox" name="sign[]" />
<input value="5" type="checkbox" name="sign[]" />
<input type="submit" />
</form>
$("#myForm").submit(function() {
var checked_array = new Array();
$("#myForm input").each(function() {
if ($(this).is(":checked")
checked_array.push($(this).attr("value"));
});
if ( checked_array.indexOf(2) !== -1 && checked_array.indexOf(5) !== -1)
("#myForm").attr("action", "/url1.php") ;
else if etc...
});
Is it possible to conditionally add hidden input fields into a form?
eg I have a php form that is adding values to a table and if the appleID = 1 or 2 then I want 1 added to the fruits column of my table and if appleID =3 I want 1 added to the sweets column of my table. I thought I might be able to do something like the below but it is adding all hidden values no matter what I select. Or should I approach this a different way?
<input type="radio" value="1" name="appleID" />
<input type="hidden" value="1" name="fruits" />
<input type="hidden" value="0" name="sweets" />
<input type="radio" value="2" name="appleID" />
<input type="hidden" value="1" name="fruits" />
<input type="hidden" value="0" name="sweets" />
<input type="radio" value="3" name="appleID" />
<input type="hidden" value="0" name="fruits" />
<input type="hidden" value="1" name="sweets" />
Thanks I haven't done much with php so I will need to explore that option further. Thanks for the feedback.
I was also looking at something like the below. But PHP sounds likes the better option.
change field value when select radio buttons
You can either use all values in the radio buttons (1,1,0 - 2,1,0 - 3,0,1) and split them after receiving them in your PHP script or add/delete the hidden fields via JavaScript.
Split Example:
HTML:
<input type="radio" value="1,1,0" name="appleID" />
<input type="radio" value="2,1,0" name="appleID" />
<input type="radio" value="3,0,1" name="appleID" />
PHP:
if (!empty($_POST['appleID']))
{
list($appleID, $fruits, $sweets) = explode(",", $_POST['appleID']);
}
It is better to put that logic into the PHP script instead of using Javascript - because you have to do the validation anyway.
hi i have multiple option in check box and when visitor or customer select multiple option then how i can get multiple values? plz explain with code thanks
Name the checkboxes with [] (or PHP will drop all but one of them (I don't recall if it is the first or last)).
<input type=checkbox name="foo[]" value="some value">
Then they will be accessible as an array in the $_GET or $_POST superglobal.
$_GET['foo'][]
Basically, set all the name tags to be the same for all your checkboxes (with []). Then in your script, the values will be available as an array
Html:
<input type="checkbox" name="tags[]" value="1" />
<input type="checkbox" name="tags[]" value="2" />
<input type="checkbox" name="tags[]" value="3" />
<input type="checkbox" name="tags[]" value="4" />
PHP:
print_r($_REQUEST['tags']);
Reference: http://www.kavoir.com/2009/01/php-checkbox-array-in-form-handling-multiple-checkbox-values-in-an-array.html
Like this
<input type="checkbox" name="foo[]" value="bar" />
<input type="checkbox" name="foo[]" value="baz" />
<input type="checkbox" name="foo[]" value="qux" />
<?php
print_r($_POST['foo']);
