[RESOLVED] md5 -> hash issue, form

[cirma]

Hi,

I'm trying to make a form where a surfer can enter a list of words in a text box, then the script spits out the words and their corresponding md5 value in a table. But I end up with it just doing the first letter of the first word they entered.

Here's my code:

<?php 
$data=''; 
if (isset($_POST['data']) && strlen($_POST['data'])>0) { 
    $data=$_POST['data']; 
} 
if (isset($_POST['submit'])) 
{ 
    if (strlen($data)>0) 
    { 

    $newarr = explode("\n\r", $data);
    print '<b>Results</b><br><br>'; 
    print '<table width = "800" columns = "2" border = "2">'; 
    foreach($newarr as $line) 
    { 
        print '<tr>';
        print '<td>';
        print $newarr{$line};
        print '</td>';
        print '<td>';
        print md5($newarr{$line});
        print '</td>';
        print '</tr>';
        } 

    print '</table><br><br>'; 
} 
else 
    print '<b>You need to enter some data</b><br><br>'; 
} 
?> 
<b>Enter data here</b><br><br> 
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>"> 
<textarea name="data" rows="15" cols="100"> 
<?php echo $data; ?> 
</textarea> 
<input type="submit" value="Submit" name="submit"> 
</form> 

I've tried diff combinations of \n\r but I think what's happening is I'm not getting to the next line? Any ideas?

Just to be clear, I want to md5 each individual line in the box...

so they enter like:

word1
blah
meh

and then the script spits out

word1 fkgjdfkgjf98454b
blah rRmfgTlfm459839t
meh j453fjvBEmtltjk

etc.

thanks

1. It should be \r\n (for Windows systems). For best portability, you could use [man]split[/man] with a pattenr like /\r?\n|\r/ .

2. You need to look up the way a [man]foreach/man statement is used. It loops through an array and returns values one at a time. In your example, you simply need to use the $line variable, as this holds the values of the array items in the loop.

bradgrafelman,

1. Ok I tried it before like preg_split("/\r\n|\n|\r/", $data); but when I did that, it only did md5() on the first letter of the array each time in the loop? That looks correct to me but I dunno? So I thought the problem was that I should use explode() instead nad make it simpler.

2. I tried using $line before but then what it does is calculate the md of the entire contents of the array, not line by line.

What am I doing wrong here? 🙁

[bradgrafelman]

Use [man]preg_split/man as you've described. Also, only use $line in the loop.

If that doesn't work, post a new copy of your code so I can see what you're trying.

That worked 🙂

Thank you.
