Help in passing values to $_post[]

[dgrooven]

Hi,

I am having a php form say a.php which send its values from the textfields on the form to another php form say b.php for processing and send the data as an email. I have tried it with a simple email which contain a short message and it works fine.
However, it gets complicated when the data I am passing from a.php to b.php comes from an array. I use a for loop to generate the name for the $_post[] but it is not getting the values. Below are several lines of the codes I am doing:

for ($i=1;$i<=5;$i++)
{


$date_req = $_POST["date".$i];
$event = $_POST["$event".$i];
$requirements = $_POST["$req_".$i];

echo $i.$date_req.$event.$requirements;

}


I have checked all the names, they are all correct.
The above code does not display anything. I guess the format I am using for the $_post is not valid. If anyone can guide how should I do it.
Thanks in advance.

What output does this give you?


<?php
echo '<pre>' . print_r($_POST, true) . '</pre>';
?>

hi nica_swd,

thanks for the reply.

The line of code u gave me does not produce any visible output.

The problem's coming from "a.php" - it's not adding post variables. Paste the code form "a.php" and I'll have a look.

hi,

below is a piece of code from a.php
note: my b.php is actually 'send.php'

the whole code is too long, so i have sent only a part where the input fields are:


<form name="form_booking" method="post" action="send.php" >

Please note that when I call the variables one by one by their respective name using the $_post[], there's no problem. e.g if i use echo $_post[date1];
it displays me the date value i have entered on a.php. Since i have more values than that which should be passed from a.php to send.php, it need to use a for loop to reduce the lines of codes...


thanks lot

I can't see why the POST array would be empty if you can get it to work by specifying individual elements, maybe I misunderstood. You're definitely right about needing a for loop in your a.php, in fact you could use a few and cut down the <option > bits too. Quite a few of your <select > tags don't have the 1 and 2 at the end btw, e.g. <select name="num_guards_"Also, your <select > tags shouldn't have a value.

Could you PM me a link to your "a.php"? Adding <?php
echo '<pre>' . print_r($_POST, true) . '</pre>';
?> to the top of "send.php" would help too.

hi guys,

Thanks for the help.
I have gone through my lines of codes again and did find some errors in naming. So now it's working properly.

Thanks for the help.
