mikesta707 Posted April 23, 2010 Share Posted April 23, 2010 the point of output buffering is to store any output from the script into a buffer. When output buffering is active, there is no output sent from the script. if you want to send the output when using output buffering, try using ob_end_flush() check out ob_start() for more information Link to comment https://forums.phpfreaks.com/topic/199546-cant-get-function-to-work-proper/#findComment-1047371 Share on other sites More sharing options...
Baez Posted April 23, 2010 Share Posted April 23, 2010 Don't use ob_start() if you want instant output. I'm not sure if you mean outputting to the display page or simply to the HTML code. But you're also not outputting anything. And you haven't closed the <a> tag beginning. Right now it looks like <a href="index.php?act=topic&id=1"</a> Whereas it should be <a href="index.php?act=topic&id=1">index.php?act=topic&id=1</a> Link to comment https://forums.phpfreaks.com/topic/199546-cant-get-function-to-work-proper/#findComment-1047374 Share on other sites More sharing options...

mrMarcus Posted April 23, 2010 Share Posted April 23, 2010 did you correct your <a> tag as Baez pointed out? just can't see 'cause you're not actually providing your "full" code as your function is in global.php i presume.
