[SOLVED] Why does it do what it does?

[MadTechie]

No

 

you need to add the code just after you //Content has value

 

<?php
if(isset($_POST['content'])) { //Page was submitted
    if (!$_POST['content']) { //value of content is empty
        $output = "There was no data entered!";
        echo $output;
    } else { //Content has value
        echo "<input name='temp' type='hidden' value='$temp' />";
        if(($_POST['temp'] != $_SESSION['tmp1']) )
        {
        //the block in Content has value goes here
        	//Content has value
                $content = $_POST['content'];
                $info = $_POST['info'];    

                $content = language_filter($content); 

                @$fp = fopen("project4.txt", "a");
                fwrite($fp, $content."\r\n");
                $info = file('project4.txt');
                for ($i = 0; $i < count($info); $i++) {
                   echo '<br><hr>';
                   echo nl2br(htmlentities(stripslashes(trim($info[$i])),ENT_QUOTES));
                }
                fclose($fp);
            }
        }
        $_SESSION['tmp1'] = $_POST['temp'];

?>

Ok, It entered data once. Then I refreshed the page and tried to enter

data again and it would not display the data and it did not enter it into the

text file.

 

Example: Try it yourself

[MadTechie]

do you have

<?php
session_start();
?>

 

 

at the start of the page ?

 

can you post the full page code again please

[Trium918]

I have

<?php session_start(); ?>

at the start of

the page. Do you want me to delect then reinsert it again?

[Trium918]

Waldir, could you have a look at my code, or anyone who

can help? I am getting duplicates when the page is refreshed.

[Waldir]

seems to work fine here http://www.mylabserver.com/242/morris/projects/project4.php

 

[Trium918]

Enter the data and then refresh the page.

[Waldir]

show me your code.

[Trium918]

This is the code.

It's entering data into the text file but it is not

displaying it in the browse.

seems to work.

Thanks.

[Trium918]

Could someone please explain the code that was

inserted into my code?

 

<?php
session_start(); //Explain
$_SESSION = 'isset';//Explain
header( "Location: " .$_SERVER['PHP_SELF'] );//Explain

if(isset($_SESSION)) {//Explain
echo 'Form was posted';
$fp = fopen("project4.txt", "a");
$info = file('project4.txt');
for ($i = 0; $i < count($info); $i++) {
      echo '<br><hr>';
      echo nl2br(htmlentities(stripslashes(trim($info[$i])),ENT_QUOTES));
}
fclose($fp);
unset($_SESSION);//Explain
}
?>

read up on sessions

 

http://uk2.php.net/manual/en/ref.session.php

[redbullmarky]

slightly off topic. when posting lots of code, please use the

tags instead of the

tags as it makes things a tonne easier to read.

 

cheers
