[SOLVED] Why does it do what it does?

[Trium918]

Every time a user refreshes this program it creates a

duplicate of the last post and adds it to the blog.

How can I fix it?

 

Try it out by posting to the blog and

then refresh the page.

Example: Click here

 

<form method="POST">
<table border="1" align="center" width="300">
  <tr>
    <td colspan="2" align="center">How to Change the World?</td>
  </tr>
  <tr>
    <td align="center"><img src="../images/atlas.jpg" width="100" height="165" /></td>
    <td><textarea name = "content" cols="50" rows="10"></textarea></td>
  </tr>
  <tr>
    <td colspan="2">
<?

function language_filter($string) { 
   $obscenities = array("curse","word"," foul ","language"); 
    foreach ($obscenities as $curse_word) { 
        if (stristr(trim($string),$curse_word)) { 
            $length = strlen($curse_word); 
            for ($i = 1; $i <= $length; $i++) { 
                $stars .= "*"; 
            } 
            $string = eregi_replace($curse_word,$stars,trim($string)); 
            $stars = ""; 
        } 
    } 
    return $string; 
} 

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
        $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);
    }
}
?>
</td>
  </tr>
  <tr>
    <td colspan="2" align="center"><input type = submit name="submit"></td>
  </tr>
</table>
</form>

After the blog is posted re-direct them using get to another page, this will wipe out the post information they entered.

[Trium918]

Ok, If I Redirect the user will never get a change to view

their post. This is another problem that I am having. I am

not able to view a post unless the user enters a new post.

[Trium918]

Where are all those smart php programmers?

[DeathStar]

Search google for a timed redirect.

There is one on phpfreaks.com aswell!

 

And frost110 is kind smart!

Momma always said life is like a box of chocolates...you never know what flavor you are.

[DeathStar]

:-\ What does that mean?

Chocolates + Me =

Ok guys, this is what I am trying to do. I want the user to

be able to post to the blog without having to redirect just

to clear the cache. Also the user isnt allowed to view the

the last post unless they enter a new topic. I want similar to

phpfreaks forum. This is for a school project, so I am not able

use phpbb or any other forum or blog software. I not able to use

a database neither.

[DeathStar]

How do you mean?

[Trium918]

Please read reply #7

 

Also the user isnt allowed to view the

the last post unless they enter a new topic.

 

Example of my problem: Click Here!!!

[DeathStar]

So its homework?

 

if you only wan them to post once per blog use:

 $chk_ip_dup = mysql_query("SELECT * FROM users WHERE ip='{$IP}'");
     if (mysql_num_rows($chk_ip_dup))
     {
          exit ("<b><font color=red size=+1>Onlt one post allowed!</font></b>");

     }

[Trium918]

Its only a text file. There is no database being used.

[DeathStar]

oh  :-X

[cmgmyr]

why don't you just clear the variables after you write it to the file?

 

$variable = '';

[Trium918]

Clearing the variable makes since. but where would

I insert it.

[MadTechie]

add

<?php
fclose($fp); //<--- after this
unset($_POST['content']); //<---this

?>

[Trium918]

Even when I unset($_POST['content']) I am

still getting duplicate posts when the page is

refreshed.

[MadTechie]

what about adding a session, to stop them ie

 

<?php
session_start();
?>
<form action="" method="post">

<?php
$temp = rand(1,1000);
echo "<input name='temp' type='hidden' value='$temp' />";
if(($_POST['temp'] != $_SESSION['tmp1']) )
{
echo "COOL";
//add entry etc
}else{
echo "BAD";
//don't add
}
$_SESSION['tmp1'] = $_POST['temp'];


?>
<input name="" type="submit">
</form>

[Trium918]

Why would there be a random variable?

$temp = rand(1,1000);

[suzzane2020]

Insert this header function just after the script to post the topic.

header("location:samepage")

The header will redirect the user to the same page.and i guess the post data wud be wiped off

[MadTechie]

the random number is just a quick cheap way of check to see if the current post data has been sent already, its just a sample script and it works

[Trium918]

I still having solve my problem with this program.

Can anyone help. Please read reply # 7 for an

example.

[Trium918]

The page cannot be refreshed without resending the information.

Click Retry to send the information again,

or click Cancel to return to the page that you were trying to view.

 

How can I stop the php program from resending information back to the blog?

 

Example of the code:

[MadTechie]

Whats wrong with the example i gave, it works fine, their maybe a better solution but still

[Trium918]

Help me out here. Would $_POST['tmp1'] be

$_POST['content']?
