Insert information into a loop

[pianoman993]

I am having a heck a of a time trying to insert an array into an array. To illustrate this, I am using an array called $errors and trying to insert the values from $errors into an array called $problems like so: array( *errors array values here* );

 

AHH!! heelp! much thanks

Can you post the code you have already that's giving you problems between

tags?

Try the implode() function.

 

$err = implode(" ,", "$error");

 

array($err);

 

Tell me if this doesn't work, I'm not an expert.

Thanks for the help so far, I hope this code can make things more specific:

Here's one page's code:

 

	if (empty($_POST['username']))
	{
		$errors = 'Please enter your username';
	} else {
		$username = $_POST['username'];
		global $username;
	}

	if ( (empty($_POST['password'])) || (empty($_POST['conf_password'])) )
	{
		$errors = 'Please enter your password';
	} else {
		$password = $_POST['password'];
		global $password;
	}

		if ( (empty($_POST['email'])) || (empty($_POST['conf_email'])) )
	{
		$errors = 'Please enter your email';
	} else {
		$email = $_POST['email'];
		global $email;
	}

	if ($errors)
	{

		$data['problems'] = array('One','Two');
		$this->template->load('register/register_view',$data);
	} else {
		echo 'Huge Success!';
	}

 

The second page's code using information from the first page:

 

<?php 
if (isset($problems))
{
	foreach($problems as $message) echo "$message<br />";
}
?>

<b>Registration Page</b>

<div id="registration"><table>
<?=form_open('register/handle')?>
    <tr><td>Username:</td><td><input type="text" name="username" /></td></tr>
    <tr><td>Password:</td><td><input type="password" name="password" /></td></tr>
    <tr><td>Confirm Password:</td><td><input type="password" name="conf_password" /></td></tr>
    <tr><td>Email:</td><td><input type="text" name="email" /></td></tr>
    <tr><td>Confirm Email:</td><td><input type="text" name="conf_email" /></td></tr>
    <tr><td colspan="2"><input type="submit" name="submit" value="Register" /></td></tr>
</table></div><!--Registration-->

 

My goal is to somehow get out all of the values from the $errors array and insert them... $data['problems'] = new array( *right here* )

see my post above

I tried your method however I got an error message:

 

Here is what I used as my code: Message: implode() [function.implode]: Invalid arguments passed

 

$pointer = implode(",","$errors");
$data['problems'] = array($pointer);

 

It seemed I was closest when I used  print_r

Here's how I would code your pages:

 

<?php
session_start();
$errors = array();
if (empty($_POST['username']))
	{
		$errors[] = 'Please enter your username';
	} else {
		$_SESSION['username'] = $_POST['username'];
	}

	if ( (empty($_POST['password'])) || (empty($_POST['conf_password'])) )
	{
		$errors[] = 'Please enter your password';
	} else {
		$_SESSION['password'] = $_POST['password'];
	}

		if ( (empty($_POST['email'])) || (empty($_POST['conf_email'])) )
	{
		$errors[] = 'Please enter your email';
	} else {
		$_SESSION['email'] = $_POST['email'];
	}

	if (!empty($errors))
	{
                $_SESSION['errors']  = $errors;
		$data['problems'] = true;
		$this->template->load('register/register_view',$data);
	} else {
		echo 'Huge Success!';
	}
?>

 

And

<?php
session_start();
if ($data['problems'])
{
	echo implode("<br>\n",$_SESSION['errors']) . "<br>\n";
}
?>

<b>Registration Page</b>

<div id="registration"><table>
<?=form_open('register/handle')?>
    <tr><td>Username:</td><td><input type="text" name="username" /></td></tr>
    <tr><td>Password:</td><td><input type="password" name="password" /></td></tr>
    <tr><td>Confirm Password:</td><td><input type="password" name="conf_password" /></td></tr>
    <tr><td>Email:</td><td><input type="text" name="email" /></td></tr>
    <tr><td>Confirm Email:</td><td><input type="text" name="conf_email" /></td></tr>
    <tr><td colspan="2"><input type="submit" name="submit" value="Register" /></td></tr>
</table></div><!--Registration-->

 

I replaced the lines of the type "global $variable" with "$_SESSION['variable'] = $_POST['variable'], since the "global" keyword is meaningless in this context.

THanks for the code rework however, it still does not solve the problem. I may in the end just recode the pages to some sort of unconventional technique to solve the problem.
