strcmp help

[scriptsit]

I'm a little stuck with a project, and if anyone could help, it'd be much appreciated.

 

I have a situation where in an html form, I have a variable number of items being sent through post. The number is dependent on a database listing. Because I am also dealing with post values I'm expecting, I have to sift through them. How I approached the problem:

 

foreach($_POST as $k => $v){
	if(strcmp($k, 'day') == 0){
		echo "got day";  
                       <snip>
                 }
        }

 

Basically what this SHOULD do is to look at each of the keys submitted, compare each one with 'day' or a few other values that I'm expecting, and what's left in my 'else' will be the variable number of items, and I can handle them accordingly. However, what this DOES do is exit without printing a sing value. Debugging has shown me that the error in this code is here or in one of the other elseif's.

 

Does anyone have any input? I am totally stuck, and I've been looking at the problem for way too long to be productive.

 

Thanks in advance

Please post your form.

[scriptsit]

<form action="adder.php" method="post" >
	<table>
		<tr><td>Week Ending:</td><td><?php put_select_date(); ?></td></tr>

		<tr><td></td><td><strong>Update Miles</strong></td></tr>
		<?php
			$query = "select * from trucks;";
			$result = $db->query($query);
			$num = $result->num_rows;

			for($i = 0; $i < $num; $i++){
				$row = $result->fetch_assoc();
				echo "<tr><td>Truck" . $row['number'] . "</td>";
				echo "<td><input type=\"text\" name=\"" . $row['truckid'] . "\"></td></tr>";
			}
		?>

Sorry, I didn't actually put the whole form on there, just what I thought was relavent. The put_select_date(); function is one of mine, which basically gives a date selection input with today's date already highlight. The values sent are 'day', 'month', and 'year'.

 

The rest of the form is as follow:

		<tr><td></td><td><Strong>Update Fuel Meter</strong></td></tr>
		<tr><td>This week</td><td><input type="text" name="gal" />gal</td></tr>
		<tr><td>Price</td><td><input type="text" name="price" /></td></tr>
		<tr><td></td><td><input type="submit" value="Enter" /></td></tr>
	</table>
</form>

At the top of your script that processes the form, put

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

This will dump what is being sent from the form.

 

Also, you can re-write you loop as

<?php
			while ($row = $result->fetch_assoc()){
				echo "<tr><td>Truck" . $row['number'] . "</td>";
				echo "<td><input type='text' name='" . $row['truckid'] . "'></td></tr>";
			}
?>

The output (after commenting out bad code):

 

Array
(
    [month] => 05
    [day] => 30
    [year] => 10
    [1] => 100100
    [2] => 120100
    [gal] => 100100
    [price] => 3.21
)

In your "if" statement, why don't you just do:

<?php
if($k == 'day'){
		echo "got day";  
}
?>

To be honest, I thought I had an error once yielded by using == instead of strcmp. It may have been, incidentally, an error in that program, but since then I've been using strcmp to satisfy incidents where I would have used perl's 'eq'.

 

I'm not sure why your solution worked, but it has. And, since I do not like to wrestle with fortune, I shall be content knowing that it works (at least until memorial day is over).

 

Thanks for your help.
