Need a (simple) php script

[wkrappen91]

Hey guys.
Im currently working on a project for my fellow BHWlers (will share it soon) but i need one more thing and i cant figure it out.
I want the visitor of my website to be able to load a txt file and then, by clicking a button display one line of it in a textfield.
when the button is clicked again, the next line should appear.
When the end is reached, it should start over at the top.

I hope you can help me

In php I would do it with a form that includes a hidden field that pass the variable for the current line number in the file.

 

[hi.imandrew]

<?php
$file = file("filename.txt");//load contents into array which is split by each new line
//to print the 5th line of the file:
print $file[4];
?>

Thanks so far but i still cant figure it out (0 PHP skills..)
If anyone could go a little further and post the complete html/php code, i would be very very thankfull

[wkrappen91]

Hmmm, so you want everything free?

Try this

<?php
$line_no = 0;
if(isset($_POST['line_no'])) {  $line_no = $_POST['line_no']; }
$lines = file("robots.txt");
$last_line = count($lines);
if ($line_no == $last_line) {
    $line_no = 0;
    } else {
    $line_no = $line_no +1;
    }
?> 
<form name="main_form" method="POST" action="<?php echo $PHP_SELF;?>" >
<input type="hidden" name="line_no" value="<?php echo $line_no;?>">
<?php print $lines[$line_no]; ?>
<p align="center"><input type="submit" value="Next"></p></form>

Nope. I said i will give away a free scapebox blast to the one who solves it

Try this

<?php
$line_no = 0;
if(isset($_POST['line_no'])) {  $line_no = $_POST['line_no']; }
$lines = file("robots.txt");
$last_line = count($lines);
if ($line_no == $last_line) {
    $line_no = 0;
    } else {
    $line_no = $line_no +1;
    }
?> 
<form name="main_form" method="POST" action="<?php echo $PHP_SELF;?>" >
<input type="hidden" name="line_no" value="<?php echo $line_no;?>">
<?php print $lines[$line_no]; ?>
<p align="center"><input type="submit" value="Next"></p></form>

Thanks man this works.
but im missing the ability to upload your own txt(that is where i am stuck...)

How can you upload a php file but not a txt file?

 

[hi.imandrew]

<?
$file = @explode(".",strrev($_FILES['upload']['tmp_name']));
$target_path = getcwd(); //gets current working directory
if (strrev($file[0]) == "txt"){ // check to make sure file ends in txt
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target_path)) {
  //successfully uploaded
 }else{
  //error
 }
}else{
 //wrong file format
}
?>

<form method='post' action='' enctype='multipart/form-data'>
 <center>
 <input type='file' name='upload'>
 <input type='submit' value='Upload'>
 </center>
 </form>
