Trying to get name of Submit button

Hi there!

I am currently having troubles sending the name of a submit button to another page.

The code for the button is as follows;

<form method='post' action='edit.php'><input type='submit' name='ValueIamTryingToGet' style='width:48px' value='Edit'/></form>

And the request from the edit.php field is

$value=$_REQUEST['name'];
echo"Value: $value<br/><br/>";

But, the value is always blank on the paged 'edit.php'.

Could anyone please advise on how I may be going wrong?

Thanks in advance!

 

The name field is used to identify the field. The value is stores in the value attribute. The right code would be:

<form method='post' action='edit.php'><input type='submit' name='somename' style='width:48px' value='Edit'/></form>

HTML:

$value=$_REQUEST['somename'];
echo"Value: $value<br/><br/>";

PHP:

This should output the value 'Edit' from your input field identified by the name 'somename'

 

$value=$_REQUEST['[COLOR="Red"]ValueIamTryingToGet[/COLOR]'];
echo"Value: $value<br/><br/>";

Code (markup):

 

Thanks for the replies. But this is sort of the reverse of what I want to achieve.

I was planning to have an ID number that could be of any value attached to a submit button. So, the 'name' variable would be $id - which is derived from a MySQL database. $id could be anything depending on the query and there would be a table of submit buttons.

So, I cant really do...

$value=$_REQUEST['ValueIamTryingToGet'];
echo"Value: $value<br/><br/>";

as ValueIamAmTryingToGet could be anything.

Hopefully what I am trying to do makes sense.

Thanks again

 

You do it like this

$value = array_search('Edit',$_POST);

PHP:

 

I dont see how 'array search' would work in this case as I dont have an array to search from.

I am trying to get a virtually random numer that is assigned to a submit button.

 

What if I want the contents and the contents contain a random value. How would I go about getting the value of the button.

I'll give you some more background as to what I am trying to do.

I have a MySQL database that is full of 'listings'. Each listing has an auto-increment ID column.

I want to be able to view all current listings and have an edit or delete button next to each listing and then send the value of the ID through a submit button over to another page and act accordingly to the button that was pressed.

Something like

DELETE FROM Listings WHERE id=$submit_button_value

Thanks again!

 

btw - dear god, sanitize your inputs

 

$_POST is the array you search, if you print_r($_POST) you get:

Array (
 [ValueIamTryingToGet] => Edit
) 

Code (markup):

so by using

$value = array_search('Edit',$_POST);

PHP:

you get the name of the field

 

How do you mean?

If I am going about it the wrong way, I am more than open to suggestions.

 

@Narrator

Actually, I have tried what you explained and it has worked exactly as I wanted.

Thanks heaps for everyones help!

 

Well thank me that is

In the future I would try the suggestions from people before saying it doesn't work. Because you never know you could learn something new one day.

 

I dont believe I ever said that something 'didn't work'.

I will say that I didn't fully understand the answer though, until I read deeper and put it into practice.

Thanks again though.

 

is this worked ??

 

Yes, it did thanks
