[SOLVED] Explode - Implode - Which to use??

[timmah1]

When I use this, I just get Array printed out

$sportPackage = $_POST['sport'];
$sportPackages = explode(", ", $sportPackage);
for($i = 0; $i < count($sportPackages); $i++){
echo $sportPackages[$i];
}

When I user this, it prints out every sport there is, not just the ones checked

$sportPackage = $_POST['sport'];
$sportPackages = implode(", ", $sportPackage);
for($i = 0; $i < count($sportPackages); $i++){
echo $sportPackages[$i];
}

 

My input buttons are like this

<input name="sport[]" type="hidden" value="ncaab" />
<input name="sport[]" type="hidden" value="ncaaf" />
<input name="sport[]" type="hidden" value="nba" />

 

Can someone tell me the correct way?

 

Thanks in advance

foreach ($_POST['sport'] as $sport) {
  echo $sport;
}

This prints out every checkbox that is on the page.

I'm only checking two, so those two should be the only

one showing correct?

And another question,

foreach ($_POST['sport'] as $sport) {
  echo $sport;
}

why does this code work in FF, but in IE I get

Warning: Invalid argument supplied for foreach() in /home/vegas/public_html/core/billinginfo.php on line 249

Should work in both. If it does not chances are it is something with your code or you are not posting the variables right.

 

PHP knows nothing about the browser. It could be a missed tag in your HTML somewhere, and FF parses it right, but IE likes to make a fuss.

You get that warning if an array is not posted as the first part of the expression in the foreach. 

 

foreach ($array as [$key => ] $val) {...} // key is optional

 

For instance, if you don't check any options, $_POST['sport'] will not exist, and you will get that error.  The foreach loop will cycle through all of the values that are checked in your form.  It will not cycle through the ones you did not check, because they weren't sent to the script.  As far as the script is concerned, the unchecked ones don't exist. 

 

All that aside, I'm finding it kind of hard to believe that you're checking hidden input fields.

ok,

here's a partial part of my code

Notice how the sport field is labeled sport[]

<?php
if($NFLactive == "1") { ?>
        <!--start NFL table-->
        <table width="100%" cellpadding="5" border="1" cellspacing="0" height="175">

          <tr>
            <td><table width="100%" border="0" cellspacing="0" cellpadding="0">
                <?php 
$sql = "SELECT * FROM nfl WHERE active = '1' ORDER BY id";
$q = mysql_query($sql);			
while($a = mysql_fetch_assoc($q)){ 
if($a['price'] == "n/a") {
	$price = "N/A";
}
else {
	$price1 = number_format ($a['price'], 2); 
	$price = "$".$price1;
}
$packID = $a['id'];
?>
                <tr>

Now, when I post to the next page, I need it to show all of the sports that were selected.

Using what thrope said

foreach($_POST['sport'] as $sport);
	 // $sport = explode(", ", $_POST['sport']);
		echo $sport;

 

No matter what I check, nfl is always the sport, and if I check 3 boxes, it only shows one, nfl

 

Can you see what's wrong with the code?

 

Thank you again in advane

[timmah1]

oh I see Crayon, I never thought about that.

The reason it's showing all the fields is because the fields are hidden and have value, so naturally they would be showing

 

How can I get around that?

[.josh]

I don't know.  Rename your hidden fields to something else.  Take them out.  Who knows?  You haven't really been all that clear about your intentions.  Sometimes I get the impression that you just kind of dove right into the deep end of this coding business and now you're struggling to stay afloat.  I think you should back up a few steps, read some tutorials on basic principles and syntax, as well as how to debug and ask questions properly.  Not saying that to be mean; just think you'd save yourself a lot of headaches if you do. 

[timmah1]

I appreciate your response Crayon, I just stepped into something over my head, and unfortunately, I have to have it done tonight.

After this, I'm going to back off of coding for awhile.

Thanks again
