recognize "New Lines" for renaming in Textfile and count of checkboxes

[fragger]

Hi all,

In my addmail.php, I have the code for renaming an E-mail in my textfile. You click the desired checkbox and enter the new E-mail in the textfield. My problem now is, that everytime I rename an E-Mail, the New line will be droped, next to the email.
I also have problems with checking how many checkboxes are selected. "if (isset($POST['selmail[$j]'] < 1)) ". It doesn't work.

Can anyone help me , please ?

here's the code:

The Textfile:

[e-mail]
[e-mail]

This is mailreader.php

<?PHP
$reader = "emails.txt";
$mails = file($reader);

for($i=0; $i<count($mails); $i++)
{
print "<input type=checkbox name=semails[$i] value=>$mails[$i]"."<br>";
}

This is _addmail.php

include ("_mailreader.php");

$read = file_get_contents($reader);
if(isset($POST['addmailtolist'])) // the submit button
{
if (isset($POST['selmail'[$j]'] < 1)) // only 1 box should be selected
{
if(empty($POST['addmail'])) // the textfield
{
$add =$read .$POST['addmail']."\n";
$fp = fopen($reader, "w+");
fwrite($fp, $add);
fclose($fp);
}
}
}

First, look at the [man]trim[/man] function (this is mentioned on the [man]file[/man] page, if you look).

I also have problems with checking how many checkboxes are selected. "if (isset($POST['selmail[$j]'] < 1)) ". It doesn't work.
That's because [man]isset[/man] looks to see if a variable is set. No-one knows where this $j thing is coming from, so I guess you mean isset($POST['selmail']) && count($POST['selmail']==1), and if only one checkbox is selected, it's value will be $POST['selmail'][0].

Hi,

thanx so far 🙂

ooopps ...I forgot to mention the for () loop

for($j=0; $i<count($mails); $j++)
{
...
}

only one checkbox should be selected. It doesn't matter which one.
