[RESOLVED] problems returning values of an array in a function

[peanutgallery83]

I'm having some problems trying to use a return on values stored in an array once they have passed through an str_replace function.

When the code is working properly, I have a print statement on another page that should reference the class containing this function, perform the necessary things, and display the following: John Smith $9.95.

I was able to make this work by using a print_r() statement in the function, but when I changed it to a return() statement, it no longer works properly. Both codes are shown below...

The non-working code with the return() statement. This "prints" John:

function getText()
	{ 
		foreach ($this->FieldArray as $this->field)
		{
			// Find the FieldList name and replace with value ex: Replace First-Name with John
			str_replace($this->name, $this->value, $this->field); 

		// Return the results of the str_replace
		return ($this->params{$this->field} . ' ');
	} 
} 

The following code WAS working properly, and displays John Smith $9.95, which is the correct output using the print_r() statement:

function getText()
	{ 
		foreach ($this->FieldArray as $this->field)
		{
			// Find the FieldList name and replace with value ex: Replace First-Name with John
			str_replace($this->name, $this->value, $this->field); 

		// Print the results of the str_replace
		print_r($this->params{$this->field} . ' ');

	} 
} 	 

What can I do to get this to work properly with the return() statement and NOT the print_r() statement?

Thanks for any help!

Assuming those 3 words are 3 array elements, you need to build the desired string in the loop, and then return the result after the loop, something like:

function getText()
    {
        $output = "";
        foreach ($this->FieldArray as $this->field)
        {
            // Find the FieldList name and replace with value ex: Replace First-Name with John
            $output .= str_replace($this->name, $this->value, $this->field);
        }
        return $output;
    }

thank you nogdog. That was very close to what I was looking for, and I was able to finish it from there.

Much appreciated!
