Checking if link to file exist

QuestionsChecking if link to file exist
Cedric asked 1 year ago

Hello,

I am using the paid version.

here a sample of my code

$col = array();
$col[“title”] = “FILE_NAME”;
$col[“name”] = “path”;
$col[“width”] = “100”;
$col[“default”] = “<a target=’_blank’ href=’/files/msds/{path}’><img src=’../../datagrid/images/mimetypes/pdf.png’ alt=’pdf’ width=’16’ height=’16’></a>”;
$cols[] = $col;

This works fine.

I would like to know if there is a way to check if the file exist within the grid. and display another logo is it does not exist.

Thanks,

Instead of 'default' property, you can use on_data_display event. Code will be like following:
Refer demos/editing/file-upload.php line 118 for demo.

$col["on_data_display"] = array("display_icon","");
function display_icon($data)
{
	$path = $data["path"];
	
	if (file_exists("/files/msds/".$path))
		return "<a target='_blank' href='/files/msds/{$path}'><img src='../../datagrid/images/mimetypes/pdf.png' alt='pdf' width='16' height='16'></a>"
	else
		return "<img src='../../datagrid/images/mimetypes/not-found.png' alt='pdf' width='16' height='16'>"
}
