Primer iz knjige "PHP 5/MySQL Programming for the Absolute Beginner" ne radi.
Evo koda:

Code:

<html>
<head>
<title>
persistence demo
</title>
</head>
<body>
<h1>Persistence Demo</h1>
<form>
<?php
//increment the counters
$txtBoxCounter++;
$hdnCounter++;
print <<<HERE
<input type = “text”
name = “txtBoxCounter”
value = “$txtBoxCounter”>
<input type = “hidden”
name = “hdnCounter”
value = “$hdnCounter”>
<h3>The hidden value is $hdnCounter</h3>
<input type = “submit”
value = “click to increment counters”>
HERE;
?>
</form>
</body>
</html>

Ovaj programcic se nalazi na strani 116 i trebalo bi da se klikom na tipku ili svakim novim pozivom stranice uveca broj sto se ne desava.
Ova knjiga ima jos neke primere koji ne rade ( na primer kod FORM i POST ali to sam resio ) pa je ne bih preporucio pocetnicima ali kad
sam vec poceo voleo bih da je predjem. Ako neko zna u cemu je problem bio bih zahvalan na pomoci. Pozdrav

Cini mi se da ti je problem u ovim duplim navodnicima, probaj ih rucno napisat...

@zoligen - Knjiga ti je malo zastarela. Primer ne radi zato sto je u novijim verzijama PHP-a, po DEFAULT-u iskljucena opcija "register_globals".

Odradi kod ovako:

Code:

<html>
<head>
<title>
persistence demo
</title>
</head>
<body>
<h1>Persistence Demo</h1>
<form>
<?php
$txtBoxCounter = $_POST['txtBoxCounter'];
$hdnCounter = $_POST['hdnCounter'];

//increment the counters
$txtBoxCounter++;
$hdnCounter++;
print <<<HERE
<input type = “text”
name = “txtBoxCounter”
value = “$txtBoxCounter”>
<input type = “hidden”
name = “hdnCounter”
value = “$hdnCounter”>
<h3>The hidden value is $hdnCounter</h3>
<input type = “submit”
value = “click to increment counters”>
HERE;
?>
</form>
</body>
</html>

I pogledaj:

http://us2.php.net/manual/en/reserved.variables.post.php

EDIT:

Izmeni i FORM tag:

Code:

<form name='forma' method='POST' action='<?= $_SERVER['PHP_SELF'] ?>'>
<?php
$txtBoxCounter = $_POST['txtBoxCounter'];
$hdnCounter = $_POST['hdnCounter'];

//increment the counters
$txtBoxCounter++;
$hdnCounter++;
print <<<HERE
<input type = “text”
name = “txtBoxCounter”
value = “$txtBoxCounter”>
<input type = “hidden”
name = “hdnCounter”
value = “$hdnCounter”>
<h3>The hidden value is $hdnCounter</h3>
<input type = “submit”
value = “click to increment counters”>
HERE;
?>
</form>

Jos uvek zeza ali bar imam putokaz. Koju bi knjigu preporucio?
Hvala na odgovoru.

Sta tacno zeza ? :-)

Preporucio bih ti (k'o sto bi ti svako drugi preporucio :P) - PHP Documentation

EDIT:

Code:

<form name='forma' method='POST' action='<?= $_SERVER['PHP_SELF'] ?>'>
<?php
$txtBoxCounter = $_POST['txtBoxCounter'];
$hdnCounter = $_POST['hdnCounter'];

//increment the counters
$txtBoxCounter++;
$hdnCounter++;
echo "<input type = “text” name = “txtBoxCounter” value = '$txtBoxCounter'>
<input type = 'hidden' name ='hdnCounter' value = '$hdnCounter'>
<h3>The hidden value is $hdnCounter</h3>
<input type='submit' value = 'click to increment counters'>
"
?>
</form>

Sad bi trebalo da radi :-)

Ja bih ti preporucio PHP i MySQL:
razvoj aplikacija za Web, prevod 4. izdanja ako te vec zanimaju PHP i MySql.

Izvinite na neozbiljnosti bavio sam se nekim drugim stvarima pa nisam navracao ovde.
Prvo ovaj primer nikako da proradi, sad kad sam ubacio ovaj poslednji deo koda daje mi:

Notice: Undefined index: txtBoxCounter in C:\Program Files\EasyPHP 3.0\www\10min\SAM SEBE\index.php on line 13
Notice: Undefined index: hdnCounter in C:\Program Files\EasyPHP 3.0\www\10min\SAM SEBE\index.php on line 14

Neznam kako da omogucim "register_globals", mozda je u tome problem.
Da li bi ti Man-Wolf mogao da napises programcic koji kod tebe radi pa da ne
gubim vreme vise.
Mozda sam malo glup ali sve ostale primere sam odradio ( promenljive, stringovi, nizovi, fajlovi) jedino gde se koristi
ovakvo pamcenje promenljive po napustanju stranice, nece da radi.
Sto se tice knjige "PHP i MySQL razvoj aplikacija za Web" ima li je negde na net-u? Nema u knjizarama a u mikro knjizi oce da me stave u neki red za cekanje
pa ako im vrate neki zaostali primerak da me obaveste.
Pozdrav!

Nemoj da ukljucujes register_globals ;)

Code:

<form name='forma' method='POST' action='<?= $_SERVER['PHP_SELF'] ?>'>
<?php
$txtBoxCounter = isset($_POST['txtBoxCounter']) ? $_POST['txtBoxCounter'] : 0;
$hdnCounter = isset($_POST['hdnCounter']) ? $_POST['hdnCounter'] : 0;

//increment the counters
$txtBoxCounter++;
$hdnCounter++;
echo "<input type = “text” name = “txtBoxCounter” value = '$txtBoxCounter'>
<input type = 'hidden' name ='hdnCounter' value = '$hdnCounter'>
<h3>The hidden value is $hdnCounter</h3>
<input type='submit' value = 'click to increment counters'>
";
?>
</form>

Note: Ukoliko ti nije jasno sta znaci ovo: $txtBoxCounter = isset($_POST['txtBoxCounter']) ? $_POST['txtBoxCounter'] : 0;

Code:

$txtBoxCounter = isset($_POST['txtBoxCounter']) ? $_POST['txtBoxCounter'] : 0;

// je skraceni zapis od:

if (isset($_POST['txtBoxCounter']))
{
$txtBoxCounter = $_POST['txtBoxCounter'];
else
{
$txtBoxCounter = 0;
}
