preview string with strlen PHP (help)

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

I'm currently not sure why your first piece of code isn't working, but
the second is quite simple. You aren't returning any variable in your
function, and so it won't output anything. Add the following:
return $previewtext;
Just before the }

Then it will return something, but i think not what you wanted to :(

Hi Dwayne,

Your function isn't working as you expect because you are not returning any
value. I would rewrite it as:

function previewString($strInput) {
// Max length allowed
// You could also store this in a config file or pass in as
// a second, possibly optional argument.
$intMaxLen = 235;

if (strlen($strInput) > $intMaxLen) {
// Too long so trucate it (and add ... to show
// it is truncated. I subtract 3 to allow for ...)
return substr($strInput, 0, ($intMaxLen-3)).'...'
}

// If we get here it is less than or equal to the allowed max so just
return it
return $strInput;
}

You would then call the function when you needed the truncated string, e.g.
<?php echo previewString($previewstext); ?>

If you are outputting this to a web page, you'll probably also want to pass
it through the htmlentities function: <?php echo
htmlentities(previewString($previewstext)); ?>

Good luck,
Edward

the above variable assignment is superfluous.

the above variable assignment is very wrong
(unless you intend to set $previewtext to NULL right after
you have just done the 'hard' work of creaating it).

>

you have no return statement in your function so it will never give you
a value - some other languages implicitly return the value of the last expression
in a function (e.g. Ruby IIRC) but php requires that you explicitly
use 'return' to pass a variable back to the code that called the function.

note also that the variable named inside the function have nothing to do with
variables named outside the function - this is called variable scope ...
you can reference a variable in the global scope (i.e. one defined in
the outer most level of code by using the 'global' keyword), an example

<?php

function myFunc() {
global $foo;

$bar = "boohoo :-(";

echo " ...INSIDE: ", $foo, " ", $bar;
}

$foo = "tada!";
$bar = "haha!";

myFunc();
echo " ...OUTSIDE: ", $foo, " ", $bar;

?>
> }

have a look at this:

function previewString($showcatvar)
{
// sanity check on the input
if (empty($showcatvar) || !is_string($showcatvar))
return "";

// get the string size
$len = strlen($showcatvar);

// long strings will be truncated to 235 chars
// BTW - this will really bite you in the ass if
// the string contains HTML (think about unclosed tags!)
if ($len > 235)
return substr($showcatvar, 0, 235);

// strings less than or equal to 235 in length
// are shown as is
return $showcatvar;
}

Dear all,

hmm.. sorry the $previewstext thing was a typo in my mail.

But yes it is working but it will only display the first record of the
recordset. I have like a list for items with short text in a page and of
course made a query to make the database variables available. Which where
the variable $row_show_cat['text']; comes from.

This is why I thought that i may have to rewrite it into a function to
display the $row_show_cat['text']; in a repeated reagion.


I have rewritten my function:

<?php
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;

return $previewtext;
}
?>

And to to show it later in the page:
<?php echo previewString($row_show_cat['text']); ?>
but this still won't anywould display anything. :S

Please let me know.

what is the meaning of the above line???
you are giving an undefined value (default NULL) to $previewtext, just
after you gave it the right value
delete that line and you might be well

In your function there is at the end before the return statement:
$previewtext = $whowcatvar;
First $whowcatvar isn't defined. So it could be an answer.
And I think u need to delete this line.

YES this works thank nemeth:

<?php
function previewString($showcatvar) {

$minitxt = $showcatvar;
$len = strlen($minitxt);

if ($len > 235)
{
$len = 235;
}
else
{
$len = $len;
}

$newstring = substr($minitxt,0,$len);

$previewtext = $newstring;

return $previewtext;
}
?>

and to display it:

<?php echo previewString($row_show_cat['text']); ?>

cheers

Dwayne

> YES this works thank nemeth:

your welcome but please call me Zoltán ;)
(my first name is Zoltán. in Hungary we write names the opposite order
than anywhere else ;) so that's why my mailbox is set to display 'Németh
Zoltán' but I sign my mails as 'Zoltán Németh' showing that my first
name is Zoltán and last name is Németh :) )

greets
Zoltán Németh
