    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>';
?>

    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" >
    <tr>
    <td bgcolor="#ffffff" valign="top">








    <table cellpadding="4" cellspacing="0" border="0">
    <tr>
    <td colspan="2">


    <table style="margin:1em 0 1em 0">
    <tr valign="top" id="ts_headings" >
    <td><b> No.</b></td>
    <td><b> Date</b></td>
    <td><b> Start-Time</b></td>
    <td><b> End-Time</b></td>
    <td><b> Guards</b></td>
    <td><b> Event Type</b></td>
    <td><b> Notes (if any)</b></td>

    </select>
    </td>
    <td><input type="Text" name="req_" value="" size="20" /></td>

    </tr>




    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_"
    HTML:
    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>';
?>
    PHP:
    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.
