PHP HELP

[driz]

initial problem fixed, see further down. x

I see 4 posts and none of them really look different from the other ones.

[driz]

okay i dunno why, but the posts are appearing, but we keep getting a random one added as well, which is blank with a / in the date bit, why is a blank one being added? thanks.x

[justsomeguy]

You have blank lines in the text file that the PHP script thinks are a separate post. You split up the text file into lines and then treat each line as a post. Either remove the blank lines in the text file or change the script to check if the line is blank before it prints a post.

How do i check for blank posts before printing them?Also how could i add small delete buttons to the posts that i can click to delete.THANKS

[justsomeguy]

Instead of this:if(!empty($line))Do this:if (trim($line) != "")Deleting isn't very easy with a text file-based system, at least compared to a database. You'll need to print delete links with a counter where you count each post. So you will need a counter variable that gets incremented whenever you print a post that you can attach to a delete link, something like this:<a href="index.php?mode=delete&post=<?php echo $counter; ?>">delete</a>The PHP script will need to check the $_GET['mode'] variable to see if it equals "delete", get the $_GET['post'] variable to see which post to delete, and then count through the file until you find that post. If you use the file function to read the file into an array, you can just delete that array element and write the array back to the file, or something like that.

any updates?

If you want to alternate between two things you can use mod.

$nr = 0;while (...){  if ($nr % 2)  {	// choice 1  }  else  {	// choice 2  }	  $nr++;}

[driz]

where abouts in the code does that go? and what goes in the while loop? thanks. x

[justsomeguy]

That code doesn't go anywhere, it's an example of how to use the mod operator and a counter to decide between 2 cases. You already have a foreach loop there, you can add a counter and use mod to figure out which case you're in.

You could even just flip between true and false for a variable:

$nr = true;while (...) {  if ($nr) {	// choice 1  } else {	// choice 2  }	  $nr = !$nr;}

This may be slightly faster than incrementing the variable.
