Recall Stored Data for login

[TheJoey]

Here is my code so far

<?php

$email = $_POST['email'];
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$age = $_POST['age'];
$address = $_POST['address'];
$city = $_POST['city'];

$fp = fopen("data.txt","a");

if(!$fp) {
    echo 'Error: Cannot open file.';
    exit;
}

fwrite($fp, $email."||".$fname."||".$lname."||".$age."||".$address."||".$city."\r\n");

fclose($fp);
?>

 

im having real trouble reclaiming that text for a login script.

Could anyone start me off.

Storing logins in text files is not recommended. It is very insecure. You are better of using a database.

[TheJoey]

Cant use a database because of database restrictions something i should of checked before i paid for it.

Is there a way to do it?

[TheJoey]

<?php
    readfile("data.txt");
?>

 

is to read the file althought it reads it with | inbetween everything.

But how do i make that information passible between scripts etc

[wildteen88]

I'd use file instead. file returns an array of lines. Then you can use a loop to easily check each line.

 

$lines = file('data.txt');

foreach($lines as $line)
{
    $bits = explode('||', $line);
    echo '<pre>'.print_r($bits, true).'</pre>';
}

Wow huge help.

Thank you.

say i wanted every [0] to be user name would that be possible?

 

Array
(
    [0] => @
    [1] => joe
    [2] => joe
    [3] => 124
    [4] => joe
    [5] => joe

)

??? Post your question more clearly.

[TheJoey]

well i was thinking of going to make everyone [0] a username and [1] a password from my stored information. How would i go about doing so?

Array
(
    [0] => joe@joe
    [1] => joe
    [2] => joe
    [3] => 21
    [4] => as
    [5] => as

)

Array
(
    [0] => joe@joe
    [1] => joe
    [2] => joe
    [3] => 21
    [4] => as
    [5] => as

)

 

so [0] => joe@joe would be my username and

    [1] =>joe would be my password

[TheJoey]

<?php
$userinfo = file("data.txt");

   echo '<table>';

foreach($userinfo as $key => $val) 
{
   $data[$key] = explode("||", $val);
}

for($k = 0; $k < sizeof($userinfo); $k++) 
{ 
   echo '<tr><td>Username:</td><td>'.$data[$k][0].'</td></tr>';
   echo '<tr><td>Password:</td><td>'.$data[$k][1].'</td></tr>';
   echo '<tr><td colspan=2> </td></tr>';
}

   echo '</table>';
?>

 

This is displaying it a little easier to explain i think.

Username: joe@joe

Password: joe

Username: joe@joe

Password: joe

 

[Garethp]

Why not just

 

foreach($data as $v)
   {
   echo '<tr><td>Username:</td><td>'.$v[0].'</td></tr>';
   echo '<tr><td>Password:</td><td>'.$v[1].'</td></tr>';
   echo '<tr><td colspan=2> </td></tr>';
   }

[TheJoey]

Effectively its the same isnt it?

i still need a way to push this information for a login

 

How would i take the username and use it

and take the password and use it

[Garethp]

if($d[0] == $Username && $d[1] == $Password)

{

//Log them in

}

[TheJoey]

Im unsure how i would apply this could you give me a example

 

ill most likely create a form.

in html and post it via .php

[TheJoey]

was thinking something like this for the form.

Having trouble using the code you gave me to proccess the login

echo '<table>
<tr><td>Username<br>
<form action="read3.php" method="post">
<input name="username" type="text"></td></tr>
<tr><td>Password<br>
<input name="password" type="password"></td></tr>
<tr><td><input value="Submit" type="submit"></td></tr>
<tr><td><a href="register/index.php">Register</a></td></tr>
</table>';
