$_POST identifier

[suohryu]

Hi all long time since i been here hope everyone is keeping cool

 

so it has come to me lately that i should be able to do this but cant figure out how

what i am trying to do is use the $_Post array in a way so i can auto generate forms on the flybut i need to be able to do one thing i cant figure out which is how to do

1 echo the variable identifier

that's it and what i mean is

say i had a input called "name"

 

now what i want to be able to do is something like this

echo "my". <Missing bit> ." is ". $_POST['name'];

which in the public say something like

my name is bob

 

now this is probably a very simple thing to do and if anyone knows i would be very grateful

This is basic HTML with PHP. See the above tutorial for more information about it.

Are you looking for something like this?:

 

<?php
$str = 'name';
echo "my $str is " . $_POST[$str];
?>

 

Or you could loop through the post array like this, getting access to both keys and values:

 

<?php
foreach ($_POST as $key => $value) {
   echo "The value associated with the key '$key' is '$value'.<br />";
}
?>

[suohryu]

<?php
foreach ($_POST as $key => $value) {
   echo "The value associated with the key '$key' is '$value'.<br />";
}
?>

 

thank you this is exactly what i was after so thank you

 

are you able to explain this code at all tho in terms of how it works

$_POST as $key => $value

You're welcome. That's just one of the two syntaxes of a foreach loop. Could be translated to: Loop through each element of the array $_POST, and assign the key to $key and the value to $value on each iteration.
