Hello I have the following form that collects data entered and later I output it. It works just fine when I use POST but when I use REQUEST like the teacher said to do, the echo $word comes back empty. Any ideas guys? please?
<Form name ="form1" Method ="REQUEST" Action ="">
<Input Type = "text" Value ="<?php echo $word ?>" Name ="word">
<Input Type = "Submit" Name = "Submit1" Value = "Submit">
<?php
if (isset($_POST['Submit1'])) {
$word = $_POST['word'];
$book = $_POST['book'];
}
?>
There is no method called REQUEST on a Form. It should be either GET or POST
Maybe your teacher is confused with the $_REQUEST in PHP.
I think you are looking for GET, not REQUEST.
GET will include the contents of the form submission in the URL itself, so it's suitable for things that should be able to be bookmarked, like search form submissions.

Not sure why your teacher asked you this, but "REQUEST" is not a standard HTTP method so I don't think there's any shortcut in PHP to retrieve the data. I found that even using PATCH sometime causes problems.
What you could try is to read the raw data directly using:
file_get_contents("php://input")
There is NO method named REQUEST. You can use only two methods : POST and GET.
If you are using POST as method, you can get the values using only POST OR REQUEST.
If you are using GET as method, you can get the values using only GET OR REQUEST.

I have used this page http://www.binarytides.com/blog/php-redirect-go-back-to-previous-page/
to go back
but from
http://page.co/test.php?item=26
I post something to post.php and then call the php Go back function but I go back to
http://page.co/test.php
losing the argument path, any idea?
In Your form fill in the query string to the action attribute, like this:
<form action="?item=26" name="myform">
...
</form>
and after the submission Your HTTP_REFERER will contain this query string so redirect to it will be successfull...
EDIT: If the form is on the page post.php, it is enough to use action="?item=26" - of course You can and should use PHP to write down the number/ID of item from whenever it may come...
Lets say Your item ID is stored in the variable $item_id - then Your action will look like this: action="?item=<?php echo $item_id; ?>".
You should use sessions for stuff like this. Set a session when posting the data and you're set.
I swear i couldn't find a simple working solution for this.
On a form i have inputs that have names containing "[]" and i cant change the names of the inputs because they are part of a script.
I want to php POST the values of those inputs at the next page, after the form submit.
Example of input
<input type="text" name="CustomFields[13]" id="CustomFields_13_1" value="">
Anyone knows how to accomplish it?
I want to do it using PHP only
If the name is CustomFields[13], then you can access it at $_POST['CustomFields']['13'].
You "cannot" POST something with PHP. It's always the client that POSTs to the server. PHP is running on server side.
I recommend that you use sessions and save there the values that you need to have available in next pages.
This is how you set a session:
session_start();
$_SESSION['CustomField'] = "test";
And this is how you get it:
session_start();
echo $_SESSION['CustomField']; //Should display "test"
How do i set the variable that the $_GET function will be able to use, w/o submitting a form with action = GET?
$_GET contains the keys / values that are passed to your script in the URL.
If you have the following URL :
http://www.example.com/test.php?a=10&b=plop
Then $_GET will contain :
array
'a' => string '10' (length=2)
'b' => string 'plop' (length=4)
Of course, as $_GET is not read-only, you could also set some values from your PHP code, if needed :
$_GET['my_value'] = 'test';
But this doesn't seem like good practice, as $_GET is supposed to contain data from the URL requested by the client.
You can create a link , having get variable in href.
<a href="www.site.com/hello?getVar=value" >...</a>
You can use GET variables in the action parameter of your form element. Example:
<form method="post" action="script.php?foo=bar">
<input name="quu" ... />
...
</form>
This will give you foo as a GET variable and quu as a POST variable.
One way to set the $_GET variable is to parse the URL using parse_url()
and then parse the $query string using parse_str(), which sets the variables into the $_GET global.
This approach is useful,
if you want to test GET parameter handling without making actual queries, e.g. for testing the incoming parameters for existence and input filtering and sanitizing of incoming vars.
and when you don't want to construct the array manually each time, but use the normal URL
function setGetRequest($url)
{
$query = parse_url($url, PHP_URL_QUERY);
parse_str($query, $_GET);
}
$url = 'http://www.example.com/test.php?a=10&b=plop';
setGetRequest($url);
var_dump($_GET);
Result: $_GET contains
array (
'a' => string '10' (length=2)
'b' => string 'plop' (length=4)
)
If you want to fake a $_GET (or a $_POST) when including a file, you can use it like you would use any other var, like that:
$_GET['key'] = 'any get value you want';
include('your_other_file.php');
note: i must add that while this is ok for dev/test/debug, it is considered bad programming and i wouldn't recommend using this method in prod. it would be better to pass the processed values to the function/class instead of having it read the $_GET directly.
The $_GET variable is populated from the parameters set in the URL. From the URL http://example.com/test.php?foo=bar&baz=buzz you can get $_GET['foo'] and $_GET['baz']. So to set these variables, you only have to make a link to that URL.
simply write basic code to set get method value in php
Syntax :- $_GET['< get method variable name>']='';
Ex :- $_GET['send']='invoice';
You could use the following code to redirect your client to a script with the _GET variables attached.
header("Location: examplepage.php?var1=value&var2=value");
die();
This will cause the script to redirect, make sure the die(); is kept in there, or they may not redirect.
For the form, use:
<form name="form1" action="" method="get">
and for getting the value, use the get method as follows:
$value = $_GET['name_to_send_using_get'];
As #Gaurav and #Sander Marechal said, it's possible to add directly at the end of the URL the GET parameters to send to the web page. It works in the majority of cases. But unfortunately, there is an issue with that because an URL cannot accept any character. Some special characters have to be properly encoded to get a valid URL.
Suppose you have an index.php and you want to set a with the value &b= which contains special characters. When I submit the form of the following code, the URL sent is index.php?a=&b= and PHP prints Array ( [a] => [b] => ). So, PHP believes there is two parameters but I only want the parameter a.
You may also notice that the form method is set to POST because if you set it to GET the parameters at the end of the action URL will be ignored. For more details about that see this #Arjan's answer.
<form action="index.php?a=&b=" method="post">
<input type="submit">
</form>
<?php print_r($_GET); ?>
One solution could be to use the PHP function urlencode. But, as you can see in the following code it's not really convenient to use, especially if you have many parameters to encode. When, I submit this form the URL sent is index.php?a=%26b%3D and PHP prints Array ( [a] => &b= ) as expected.
<form action="index.php?a=<?=urlencode("&b=")?>" method="post">
<input type="submit">
</form>
<?php print_r($_GET); ?>
But, instead of urlencode function I recommend using hidden input. Thanks to this tag you can send GET parameters dynamically set by PHP. Besides, these parameters are automatically encoded with the URL standard. And you don't need to use & to separate several parameters: use one input to set one parameter. When, I submit this form the URL sent is index.php?a=%26b%3D and PHP prints Array ( [a] => &b= ) as expected.
<form action="" method="get">
<input type="hidden" name="a" value="<?php echo "&b="; ?>">
<input type="submit">
</form>
<?php print_r($_GET); ?>
I know this is an old thread, but I wanted to post my 2 cents...
Using Javascript you can achieve this without using $_POST, and thus avoid reloading the page..
<script>
function ButtonPressed()
{
window.location='index.php?view=next'; //this will set $_GET['view']='next'
}
</script>
<button type='button' onClick='ButtonPressed()'>Click me!</button>
<?PHP
if(isset($_GET['next']))
{
echo "This will display after pressing the 'Click Me' button!";
}
?>
I have a form that sends stuff like names and email and a message and I get it with $_POST['etc']; - But, I also want to send action=someaction as a part of the url, but I don't want to have any hidden form fields.
Can this be done?
Thanks!
Yep, just add it to your url: <form action="url.php?action=someaction" method="post">. You can retrieve them in your php script using $_GET (in this case, $_GET['action']).
action=someaction cannot be read by $_POST['whatever'] because it's submitted in a GET-Request. You can access GET and POST variables by using $_REQUEST instead of $_GET and $_POST.
To form the request, follow the answer of Spiny Norman.
If I understand you correctly, you simply need to add ?action=someaction to the action attribute of your form tag. These would be fetched from PHP by using $_GET instead of $_POST.
Example:
<form action="http://example.com?action=someaction">...</form>
and to get the value:
$action = $_GET['action'];
