Dear All,
I am very new to programming. I want to make a preview text that would
display only a part of the text that is a text field in a database.
//Begin Make preview string
$minitxt = $row_show_cat['text'];
$len = strlen($minitxt);
if ($len > 235)
{
$len = 235;
}
else
{
$len = $len;
}
$newstring = substr($minitxt,0,$len);
$previewtext = $newstring;
//End Make preview string
But if I want to display this somewhere in the page it will only display the
first record of at every text column row <?php echo $previewstext ?>
Althought I am very new to php and programming. I thought maybe I should
rewrite it into a function. But my function won't work.
function previewString($showcatvar) {
$minitxt = $showcatvar;
$len = strlen($minitxt);
if ($len > 235)
{
$len = 235;
}
else
{
$len = $len;
}
$newstring = substr($minitxt,0,$len);
$previewtext = $newstring;
$previewtext = $whowcatvar;
}
and to display it in the page:
<?php echo previewString($row_show_cat['text']) ?>
IT displays notthing. But I think I am doing somthing wrong. I am assigning
the wrong variables to the $row_show_cat['text']) ???
Please let me know
