gnawz Posted August 15, 2008 Author Share Posted August 15, 2008 The error is "undefined index sltBrand". Link to comment https://forums.phpfreaks.com/topic/119630-help-on-error-undefined-index/#findComment-617355 Share on other sites More sharing options...
JasonLewis Posted August 15, 2008 Share Posted August 15, 2008 $_POST will show nothing because you are not actually "posting" the data. Change your javascript from this: window.location.href = 'index.php?view=brandshow'; To this: document.getElementById('frmShowBrand').submit(); Then give your form tag an id attribute and set it to frmShowBrand.
