explode question

[petbar]

Need some help with something I have not done before.

I have a dynamic checkbox set up to accept userinput then post $optionsname,$optionsprice.

 

echo "<li><input type=\"checkbox\" name=\"optionslist[]\" value=\"$optionsname,$optionsprice\" /> $optionsname - $ $optionsprice - $optionsdisc</li>";

 

So far no problem

$showoptions=$_POST['optionslist'];
  					if(empty($showoptions))
					 {
   					 echo("You didn't select any options.");
				  }
  					else
  						{
   				 $N = count($showoptions);
   			 echo("<strong>You selected $N options:</strong> ");
    			for($i=0; $i < $N; $i++)
    			{
     		 echo("<li>".$showoptions[$i] . "</li>");
   			 }
  			}

 

Can someone tell me how to explode $showoptions into $optionsname,$optionsprice again.

 

Thanks for any help in advanced.

what are you exploding at?

 

explode

 

$showoptionsParts = explode('atsomething',$showoptions );

$optionsname = $showoptionsParts[0];
$optionsprice = $showoptionsParts[1];

[petbar]

$showoptionsParts = explode(',',$showoptions );
			$optionsname = $showoptionsParts[0];
			$optionsprice = $showoptionsParts[1];
			echo "here".$optionsprice;

 

Still nothing returned for $optionsprice.

 

Would it be an  issue if there are spaces in $optionsname ?  example ( Lock and Unlock ).  I have to be doing something really dumb that I'm just not catching

 

Thanks for the reply

what do you get when you print out $showoptions?

print_r($showoptions);

 

 

[petbar]

Array ( [0] => Lock and Unlock,29.00 [1] => Trunk Pop,19.00 )

 

so I have been trying

 

$showoptionsParts = explode(',',$showoptions );
			$optionsname = $showoptionsParts[0];
			$optionsprice = $showoptionsParts[1];
			echo "here".$optionsprice;

 

even before you suggested. That is what is driving me nuts.

 

again thanks for you time

Explode expects a string, not an array.

 

You have to loop through $showoptions, and explode each individual value.

 

You'll probably want to use foreach

[petbar]

That make a ton of sense

 

Thank you will give it a try

May I expand my question ?

 

$showoptions=$_POST['optionslist'];	

				$N = count($showoptions);
    			for($i=0; $i < $N; $i++)
    			{
     		    $showoptionsParts = explode(',',$showoptions[$i] );
			$optionsname = $showoptionsParts[0];
			$optionsprice = $showoptionsParts[1];
			echo $optionsprice."<br />";
   			 }

Works great and returns The selected option prices.  What is the best way for me to SUM the items to use further down the page. I was under the impression $showoptionsParts[1] was an array but I guess I'm incorrect AGAIN

[xyph]

Here's an example. I've used a foreach instead of the combination of count() and for() that you've used.

 

<?php

$array = array( 23,45,17,26 );
$sum = 0;

foreach( $array as $value ) {
echo 'Sum now equals '.$sum.'.';
$sum += $value;
echo ' We added '.$value.' to it, so now, sum is '.$sum.'<br>';
}

?>

 

In my example, you could use array_sum instead. Since you need to explode your values, you have to keep a running total.

[petbar]

$showoptions=$_POST['optionslist'];	

foreach( $showoptions as $key => $value){
$justprice =explode (',', $value);
foreach( $justprice as $value ) {
$sum += $value;
}
}	 

$optionsprice=$sum;

 

Thanks guys for all the help I got it

You don't need the 2nd foreach. Use $justprice[1].

thank you again  starting to clean up now.
