Collecting POST information

[Chris1981]

Hi,

I was wondering if someone could give me a hand, i have created an array for entering details into fields, and need some help pulling the information out of those boxes.

The code i have is as follows:

<form action="Now.php" method="post" name="form1" id="login" style="margin-top:0">        

<?php
for($i = 0; $i < 20; $i++)
 {
 	?>
 	<table width="100%" border="0" cellspacing="0" cellpadding="5" class="texts">
 	<tr>
    <th width="10" scope="col">Round</th>
    <th width="10" scope="col">Date</th>
    <th width="10" scope="col">Time</th>
    <th width="10" scope="col">Opposition</th>
    <th width="10" scope="col">Bye</th>
    <th width="10" scope="col">Venue</th>
    <th width="10" scope="col">Field</th>
  </tr>

  <tr>
  	<td><input name="Round<?php echo $i; ?>" type="text" class="formsBackend" id="Round"  size="2" maxlength="4"></td>
    <td><input name="Date<?php echo $i; ?>" type="text" class="formsBackend" id="Date" size="8" value="dd/mm/yyyy" </td>
    <td><input name="Time<?php echo $i; ?>" type="text" class="formsBackend" id="Time" size="4" value="h:mm" </td>
    <td><input name="Opposition<?php echo $i; ?>" type="text" class="formsBackend" id="Opposition" size="20"></td>
    <td><input name="bye<?php echo $i; ?>" type="checkbox" id="bye" value="BYE"></td>
    <td><input name="Field<?php echo $i; ?>" type="text" class="formsBackend" id="Field" size="2"></td>
  </tr>  

</table>
<hr width="75%">  

<?php } ?>
</form>

As you can see, the for statement changes the name of each field to suit how many times that it repeats.

What i need to be able to do is pull only the rows that have the "Round" value, for example, the loop goes for 20 times at the moment, and say the operator only adds 4 fields, then i only want those 4 rows so i can insert them into the database, and ditch the rest of the empty rows

Cheers

well,
you have to test the form submission.
Either in the same page (action="" ) or in another page.

you have no 'submit' button we can test first, but this you should do
or a hidden <input> with some unique name for that form

The values to test is $POST['Round0'], $POST['Round1'] etc..
for example

<?php

for($i=0; $i<20 $i++){

// remove any eventual spaces around
$round = trim( $_POST['Round'.$i] );
// test if any digit = a valid number
if( !empty($round) && ctype_digit($round) ){

    // test the other values in this row
    // and do something with row data

}
else{
    // break loop, look no further, if this row was not submitted
    break;
}
}

Hmmm ... I dont quite understand that last bit of code you submitted, thats assuming that the amount of fields will stay at 20 ... but what happens if we decide to change the number of fields to 5, then the last script will have to be changed too yeh?

That's correct. To avoid having to do that, you could use a hidden form field:
<input type="hidden" name="count" value="20"/>

Change the loop to something of this effect:

for($i=0; $i<$_POST['count'] $i++){
   ...etc
}
