I tied to send variables to another domain by using form action and it works:
<form method="post" action="http://example.com/index.php?email=FOO&subject=BAR">
In the www.example.com/index.php, it is possible print out data with:
print_r($_GET);
>Array ( [email] => FOO [subject] => BAR )
However, when I try to reach data with print_r($_POST) command in www.example.com/index.php, I get an array without values:
print_r($_POST);
Array ( [email] => [subject] => )
You may suggest using only get method or any other method, but I wonder why the post method does not work for the same pattern.

I'm trying to use this php library along with Sheetsu to pull single bits of data from a Google spreadsheet for output on a web page. My php skills are minimal and spotty, I'm afraid, and so I'm missing a final crucial component.
When I set up a test file and run my query, the code dumps everything into a $collection object. If I output print_r($collection); I get this:
Sheetsu\Collection Object (
[models:Sheetsu\Collection:private] => Array (
[0] => Sheetsu\Model Object (
[id] => 2.05.1
[title] => The Mead of Poetry
[answer] => Kvasir was created from the spit of the Aesir and Vanir. He was very wise.
)
)
)
My data's there, everything's working as expected, but I've never seen a structure like that before.
How can I just echo, say, just the [answer] value? I'm not sure what syntax to use to drill into that.
Thanks!
try
$collection->get(0)
or
$collection->getFirst()
or
$collection->getAll()[0]
etc.
models is a private property, you can't access it directly
so to access answer it would be something like
$collection->get(0)->answer
Try echo $collection[0]->answer;
I'm trying to make a custom management system for Telegram bots so that I can be able to send and read updates easily.. But my main problem is that I don't know how to retrieve data from an array. let me explain this in depth so you can understand what I'm talking about.
Basically when I try the getme command, I get this:
{"ok":true,"result":{"id":275700102,"first_name":"photoshop_post_production","username":"post_pro_bot"}}
So I converted this into an array using Php and it goes like this:
$_SESSION['website'] = "https://api.telegram.org/bot";
$_SESSION['url'] = "https://api.telegram.org/bot".$_SESSION['token'];
$_SESSION['me'] = file_get_contents($_SESSION['url']."/getme");
$_SESSION['meArray'] = json_decode($_SESSION['me'], TRUE);
So as you can see I have an array called meArray and if I print_r it ,this will be shown:
Array ( [ok] => 1 [result] => Array ( [id] => 275700102 [first_name] => photoshop_post_production [username] => post_pro_bot ) )
So basically I don't know how to take out the username or other information that I want from this array. I have tried several things but no success till now.
So, should be:
$_SESSION['meArray']['result']['username']
Try this.
I need to be able to store the $_POST data from a form (I'm doing that with the SESSION variable) and I need to add data to the $_POST array without overwriting the previous data.
Here's my original thread about the SESSION variables: Store Array Variables Through Page Refresh with PHP
Here's an example of what I need to do:
There's a form on a page that you can put the width and height of a wall to calculate out how much paint/labor would be needed to paint the walls. Once the first wall dimensions are entered, the user can click the submit button labeled "Add Wall" to add another wall to their order.
After the first wall input, the POST data would return something like this:
Array ( [wallW] => Array ( [0] => 9 ) [wallL] => Array ( [0] => 10 ) )
After the second wall is entered it would look something like this:
Array ( [wallW] => Array ( [0] => 9 [1] => 20 ) [wallL] => Array ( [0] => 10 [1] => 15 ) )
This would continue on until the user has entered all of their walls.
I've tried doing array_merge, array_append, etc, but none of those seem to be working; it keeps overwriting what's tin the POST data, even if I bring the POST data into another array.
I know the easy thing would be to throw some jQuery in there, but this is for a PHP class (and we're not allowed to use SQL yet) so I'd like to try to figure this out with just PHP.
Any help would be awesome.
Thanks,
Chelsea
I don't know why this has been downvoted, i find it rude as you are obviously new to php. But you just need to re-post your post vars in subsequent requests. So you would need to serialize you existing post objects as perhaps hidden fields. What you are missing is that php / http is stateless. So nothing is preserved between requests, another easy solution may be to move these POST variables to SESSION variables.
I see you've added the POST data to the session, but there is no reason to add it back to post, just keep appending to session and then use it from there. adding things to _POST wont force them to be posted next time if thats you are trying todo, see the part about serializing them to hidden fields.
Good luck, welcome to programming for the web.
The way you are constructing array seems little odd to me. Instead I would do something like.
if(!empty($_POST))
{
$wall = array('w' => $_POST['w'], 'h' => $_POST['h']);
$_SESSION['walls'][] = $wall;
}
Please give this a try.
I have several identical forms on a page (it's for rating stuff). The form looks like this:
<form id="contact" name="contact" action="#" method="post">
<input id="titel" name="titel">
<textarea id="msg" name="comment" class="txtarea"></textarea>
<button id="send">Send</button>
</form>
I'm sending the form data via ajax to a page where I want to store all the key=>value pairs in an array.
This is what I have on my php page where the form data is sent:
$arr = $_POST;
$array = array();
$array['titel'] = $arr['titel'];
$array['comment'] = $arr['comment'];
print_r($array);
When I send the first form prin_r gives:
Array ( [titel] => test [comment] => test2 )
Which is exactly what I want. But when I send the next form the values ar not inserted in the array, like:
Array ( [titel] => test [comment] => test2
[titel] => test3 [comment] => test4
)
In fact nothing happens. The values remain the same.
Any help much appreciated!
Mainly wrapping up the comments here.
1. Forms and request isolation
You said you submit several forms. Each time you submit form data to a PHP script, the script is executed line by line and when done, the whole process is terminated. When submitting another form, this will be another script execution which has none of the variables available you defined earlier.
This is how HTTP works. Each request is an isolated execution.
One technique to "remember" data bound to a specific client is to create a session.
A session consists of an id, which is stored on the client side, by default automatically into a cookie, and the session storage, which is saved on the server and can be reused over several isolated requests.

http://php.net/manual/en/features.sessions.php
2. Arrays in PHP
Array keys have to be unique.
Imagine - how PHP should know, which value you want to access if that would not be a unique constraint.
You said "array like several rows of a database result"
This looks like this
$result = array
(
0 => array ( 'col1' => 'colval1' ),
1 => array ( 'col1' => 'vol1val' )
)
You can do the same
$survey = array (
'step1' => array(...)
);
Access like this
$survey['step1']['..']
To save this into a session
session_start();
$_SESSION['step1'] = $survey['step1'];
To access this in a later request
print_r( $_SESSION['step1'] );
Hope this helps :)
Merry Christmas
i have a script (php+html) full of forms and inputs, after the form is submited via post i can give the user a code (like was a GET form) q=test&t=3&u=9&q2=test&t2=3&u2=9&q3=test&t3=3&3u=9, then the user can put this code in a textarea for editing what he previously submitted
how to transform the code inputed in the textarea (q&t&u) to work like if it was submitted like a normal POST? like if i where using $_POST['q'], $_POST['u'] but from that code submitted (like foreach)?
Look into parse_str
$str = 'q=test&t=3&u=9&q2=test&t2=3&u2=9&q3=test&t3=3&3u=9';
parse_str($str, $data);
print_r($data);
/*
Array
(
[q] => test
[t] => 3
[u] => 9
[q2] => test
[t2] => 3
[u2] => 9
[q3] => test
[t3] => 3
[3u] => 9
)
*/
What I understand from your question is. that you want save form and later want to allow ur visitor to update these details. Best way to do is.
you can generate a code(password) keep it in database along with record and provide it to your visitor
visitor will enter that code(unique) to get his record and can update that.
