[SOLVED] $_POST array var as numeric array?

[tarapoto]

basically, my problem is, I have a HUGE form with tonnes of inputs that I want to send to my PHP script, but I can only access the form elements in the $_POST array as an associative array, but I want to use a for loop to store all the data in a flat-file (no SQL involved here). I can also access them by the variable name for the form, but I need it as a numeric array! so I can do something like

 

for ($i = 0; $i < sizeof($_POST); $i++) {

  fwrite($fp, $_POST[$i].....)

};

 

but it only will let me access as an associative array! Is there a way to convert it to a numeric array without entering every single input name? Or at least could I maybe name all the inputs by numbers some how and convert $i to a string variable? Please help! I have searched all around the internet and I cannot find an answer to this! Any help would be greatly appreciated! Thanks

foreach ($_POST as $key => $value) {
   fwrite($fp, $_POST[$key].....)
}

foreach  example with a form set for arrays ok.

 

<form action="" method="post" enctype="multipart/form-data">
<p>Pictures:
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="file" name="pictures[]" />
<input type="submit" value="Send" />
</p>
</form>

    <?php
foreach ($_FILES["pictures"]["error"] as $key => $error) {
  if ($error == UPLOAD_ERR_OK) {
      $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
      $name = $_FILES["pictures"]["name"][$key];
      move_uploaded_file($tmp_name, "data/$name");
  }
}
?>

thanks, it's writing to the file now. But it only writes as far as the user fills out. I want it to add all the empty lines at the end so I can make sure every file is the same length even if not every input on the form is filled out...and to be honest I don't really understand exactly how the foreach structure works...otherwise I could probably figure this out on my own...I haven't needed to use PHP in ages!

^bump^ please help?

$_POST contains all fields, so I'm not sure what you're asking.

[tarapoto]

I mean, it's not cycling through to the end of the $_POST array. If I only fill out the first 20 or 30 fields or whatever, it's stops after 20 or 30 loops. I just double-checked and it actually always stops after 28 loops, no matter if I fill in every field or not

This demonstrates that they're all counted:

<pre>
<?php
if ($_POST) {
	echo 'There should be ' . count($_POST) . ' inputs:<br>';
	foreach ($_POST as $key => $value) {
		echo "$key = $value<br>";
	}
	echo '<br><a href="' . $_SERVER['PHP_SELF'] . '">Again</a>';
}
else {
	echo '<form method="post" action="' . $_SERVER['PHP_SELF'] . '">';
	$number = rand(1, 30);
	for ($i = 1; $i < $number; $i++) {
		printf('%2s: %30s', $i, '<input type="text" name="input' . $i . '"/>');
		echo '<br>';
	}
	echo '<input type="submit">';
	echo '</form>';
}
?>
</pre>

 

Do you need to check the value of empty fields before passing them to fwrite?

i got "There should be 28 inputs:" then a list up to 28...there are well over 100 inputs :-\

...I figured it out, there was a problem with my inputs, not the PHP code. thanks for all your help
