$this->load->model( adding 2 unwanted line breaks in any view/echo - El Forum - 01-21-2010

I tried this on codeigniter 1.7.2, apache 2.2 on windows vista and windows xp.

I have a simple xml webservice i am developing being consumed by a Flex datagrid component.

I want to echo out a simple xml string

in my Controller, function testflex

Code:
$xml = '';

        $xml .= "&lt;?xml version=\"1.0\" encoding=\"iso-8859-1\"?&gt;\n";

        $xml .=    "<entries>";

        $xml .=    "</entries>";

the above works fine, echos out fine

now i want to add data in.

Code:
// this is the new line that causes the output to add 2 line breaks at the start

$this->load->model('data_model');

        $xml = '';

        $xml .= "&lt;?xml version=\"1.0\" encoding=\"iso-8859-1\"?&gt;\n";

        $xml .=    "<entries>";

        $xml .=    "</entries>";

output now has 2 extra line breaks at the start that i don't want and they do cause an xml error for the consuming component.

See attached screen shots for the view of the source outputed to a browser.

You most likely have an extra line after the closing php tag in your data_model file

problem is now fixed, i got rid of the closing [code]?> [code] tag as per the style guide in my model code and it solved my problem.

There were no extra lines in my model code after the [code]?> [code] so i still have no idea why that problem was occurring in the first place.

I now have my Flex datagrid being populated by a codeigniter controller function :-)

Thanks for your help.

hi
I have the same problem. but eliminating ?> didn't help. I have no idea why $this->load->model cause an extra break line in view?

Check for whitespace before your opening php tag.
