I have two arrays. One for input boxes and other for checkbox.
inputbox[] checkbox[]
inputbox[] checkbox[]
.
.
.
.
submit button
When I fill check box1 and fill the value in input box1 and try to submit.
Foreach fails because it pass all the indexes of input boxes but only passes checked checkbox.
foreach(array_combine($checkbox, $inputbox) as $check => $input)
Please tell me what can i do?
if you have a control over the HTML form you can make the form in following manner
<input type="text" name="name[1]" />
<input type="checkbox" name="check[1]" />
<input type="text" name="name[2]" />
<input type="checkbox" name="check[2]" />
<input type="text" name="name[3]" />
<input type="checkbox" name="check[3]" />
<input type="text" name="name[4]" />
<input type="checkbox" name="check[4]" />
in that case you will get the post array in the following manner
Array
(
[name] => Array
(
[1] => Swapnil
[2] =>
[3] => Sarwe
[4] => Swapnil Sarwe
)
[check] => Array
(
[1] => on
[3] => on
)
)
Now you can loop over the name(input box) and then check isset for the isset($_POST['check'][$key]) and set the default value
Iterate over textboxes (which are guaranteed to all be present), then fetch the corresponding checkbox (probably by ID, if you have some kind of ID correspondence between them - which you should).

I have 1000 checkboxes of object fields and I want to create an Array from all the fields that I check after submitting using PHP can you tell me how to do it?
well if you name your checkbox like this, you already have an array:
<input name="mycheckbox[]" value="1"> hello1
<input name="mycheckbox[]" value="2"> hello2
<input name="mycheckbox[]" value="3"> hello3
in PHP you will get:
print_t($_REQUEST['mycheckbox']);
/*
[
0 => '1',
0 => '2',
0 => '3'
]
*/
<input type="checkbox" name="somename[]" value="somevalue"> if you need an array with numerical indices
or
<input type="checkbox" name="someobject[property]" value="somevalue"> if you are looking for an associative array
I am new to php programming language.So basically I am creating a simple form.
<?php
print_r($_POST);
?>
<form name="form1" method="post" action="">
Name: <input type="text" name="mail"><br>
Phone No: <input type="text" name="phon" /><br/>
Course:<input type="text" name="course" /> <br />
Experience: <select name="exp"> <option value="beginner">Beginner</option> <option value="intermediate">Intermediate</option> <option value="advanced">Advanced</option> </select><br>
<input type="submit" name="Submit" value="Sign Up">
</form>
So the output will be something like this:
Array ( [mail] => john [phon] => 123455666 [course] => bsc [exp] => beginner [Submit] => Sign Up )
I want to modify or change the output something like this,
Name=john
Phone No=123455666
Course=bsc
Experience=beginner
And I want to store that in the arrays, i.e. right hand side parameters in one array and left hand side parameters in another array. So that it will be easy to access or search the data. In the next level of this i want to save these values in a file.
Please help me out.
Any help or advice is appreciated. Thanks in advance.
$array1= array();
$array2= array();
foreach($_POST as $key => $value){
echo $key ."=". $value ;
echo "<br>";
$array1[]=$key; //first array for left hand side
$array2[]=$value; //second array for right hand side
}
print_r($array1); print_r($array2);
Output:-
phon=123456
course=maths
exp=intermediate
Submit=Sign Up
Array ( [0] => mail [1] => phon [2] => course [3] => exp [4] => Submit ) Array ( [0] => tet [1] => test [2] => stedt [3] => intermediate [4] => Sign Up )
Name of fields are key to $_POST array
$_POST['name_of_input']
Example:
$_POST['mail']
$_POST['phone']
Look at array_keys() and array_values()
http://php.net/manual/en/function.array-keys.php
http://php.net/manual/en/function.array-values.php
Take lessons on MySQL to store data in database
I suggest to set the names you want in the form on the first place.
Changing the $_POST is not a good practice. All it can do is confuse you and anyone else might read your code.
<form name="form1" method="post" action="">
Name: <input type="text" name="Name"><br>
Phone No: <input type="text" name="Phone No" /><br/>
Course:<input type="text" name="Course" /> <br />
Experience: <select name="Experience"> <option value="beginner">Beginner</option> <option value="intermediate">Intermediate</option> <option value="advanced">Advanced</option> </select><br>
<input type="submit" name="Submit" value="Sign Up">
</form>
Right Hand Side parameters:
$rhs_params = $_POST;
Left Hand Side parameters:
$lhs_params = array_keys($_POST);
I am not sure what you are planning to do with this tho!!
foreach($_POST as $key => $value){
#TO DO your operation
}
I just cant figure this one out:
I have a list of items:
Front and Back of Title -
Drivers License -
Vehicle Insurance -
Proof of Residence -
Proof of Income -
4 References
And a form where people check off those items.
When they press submit, I have some code that gets the values they checked, and puts them in an array like this:
Array (
[0] => Front and Back of Title
[1] => Drivers License
[2] => Vehicle Insurance
[3] => Proof of Residence
[4] => Proof of Income
[5] => 4 References
)
So the array contains any values they checked..
Here is the relevant HTML:
<input type="checkbox" name="check_list[]" value="Full Title Loan Applicaiton">Full Title Loan Applicaiton <br />
<input type="checkbox" name="check_list[]" value="Front and Back of Title">Front and Back of Title<br />
<input type="checkbox" name="check_list[]" value="Drivers License">Drivers License<br />
<input type="checkbox" name="check_list[]" value="Vehicle Insurance">Vehicle Insurance<br />
<input type="checkbox" name="check_list[]" value="Proof of Residence">Proof of Residence<br />
<input type="checkbox" name="check_list[]" value="Proof of Income">Proof of Income<br />
How would derive what values they DID not check?
Check if the item is in the array. I'm not sure how your logic is set up, but I'm assigning a variable here:
$driversLicence = in_array('Drivers License', $_REQUEST['check_list'], true);
See in_array.
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.
I have a huge form (for an internal CMS) that is comprised by several sections, some of them are optional some of them are compulsory. All is under an humungous form (it has to be like this, no ajax, no other ways :-( )
Since in a Dilbertesque way everything get changed every second I was wondering if there is any simple way of grouping $_POST data, I mean sending POST like this:
$_POST['form1']['datax']
or to retrieve data from server side easily, and by easily I mean withouth having to expressily declare:
$array1 = array($_POST['datax'],$_POST['datay'],...);
$array2 = array($_POST['dataalpha'],$_POST['dataomega'],...);
since there are around 60 fields.
I hope I was able to explain this well and as always thank you very much..
If you give your input elements array-like names, they arrive in the PHP $_POST (or $_GET) array as an array:
<input type="text" name="foo[]" value="a"/>
<input type="text" name="foo[]" value="b" />
<input type="text" name="foo[]" value="c" />
<input type="text" name="foo[bar]" value="d" />
<input type="text" name="foo[baz][]" value="e" />
<input type="text" name="foo[baz][]" value="f" />
Goes to:
print_r($_POST)
foo => array (
0 => a
1 => b
2 => c
bar => d
baz => array(
0 => e
1 => f
)
)
If you name your inputs properly, you can do that. Example:
<input type="text" name="textInput[]" />
<input type="text" name="textInput[]" />
That will populate an array in $_POST named textInput. That is:
$_POST['textInput'][0] == "whatever the first was set to be"
$_POST['textInput'][1] == "whatever the second was set to be"
Using square brackets after the input name will cause it to be grouped in PHP:
<input name="foo[]" type="text" value="1" />
<input name="foo[]" type="text" value="2" />
You can also make an associative array:
<input name="foo[bar]" type="text" />
I think multi-dimensional arrays would also work, but I'm not sure if I've actually tried it.
Edit: Here's the same thing answered in the PHP FAQ.
you can use your form fields like this:
<input type="text" name="form1['datax']"/>
