Self Validation in a form with Redirection problem

yoki

Hi,

I have a page that does a validation of required fields. Once all the fields are filled in, I want the user to be redirected to another page. I've tried using the header technique but without any result. I think the PHP_SELF is screwing it up. I am a bit confused about it actually. Could some help please? Here is my main page:

</head>
<body>
<div align="center">
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<div align="left">
<input type="hidden" name="required" value="Title,Topic" />
<table width="50%" border="0" cellspacing="1" cellpadding="0" bgcolor="#eb6093">
<tr>
<td>
<table width="60%" border="0" cellspacing="0" cellpadding="5" bgcolor="white">
<tr>
<td colspan="2"><br/>
</td>
</tr>
<tr>
<td colspan="2"><img src="images/i_abstract_information.gif" alt="" height="30" width="700" border="0"/></td>
</tr>
<tr>
<td colspan="2"><br/>
<?PHP
include_once('easyform.php');
session_register();
header("Cache-control: private");
$errorindicator='<img src="alert.gif" width="20" height="20" alt="Alert" title="Indicator for missing form element" border="0" />';
$errorclass="error";
$Javascript=true;
$results=check();
if($results[0]=='Errors:'){
?><h2 class="errorhead">There has been an error:</h2>
<p>You forgot to enter the following field(s)<?PHP foreach ($results as $i=>$e){if ($i>0){echo "<li>$e</li>";}}?><?PHP }else if ($results['Title']!=''){ gotoPage2();?>

										<?PHP }?></td>
								</tr>
								<tr>

								</tr>
								<tr>

and here is the php page: easyform.php

<?PHP
/
Easyform developer edition
version 1.0 01.05.2003
written by Chris Heilmann
more info: http://www.onlinetools.org/articles/easyform/
/
session_register();
header("Cache-control: private");

function gotoPage2()
{
$SESSION['POST_VARS'] = base64_encode(serialize($POST));
session_write_close();
header("location: abstract_page_2.php");
}

bastien

that main form is pointing back to itself...if it is I really hope its called easyform.php ...if not you will need to change the action to make it point to easyform.php

yoki

Nope, no good. It reloads my page instead of being re-located to my second page. What a drag!!! :mad:

Here is my modified code:

<?PHP
session_register();
header("Cache-control: private");

function check()
{
if ($POST['process'] == 1)
{
$sentarray=array();
$tocheck=explode(',',$POST['required']);
$error[0]="Errors:";

	foreach ($tocheck as $t)
	{
	  if(!array_key_exists($t,$_POST))
	    {$error[]=$t;}
	}

	foreach (array_keys($_POST) as $p)
	{
		if(!preg_match('/initvalue/',$p) and !preg_match('/required/',$p))
		{
			$sentarray[$p]=$_POST[$p]==$_POST[$p.'initvalue']?'':$_POST[$p];
		}
		foreach ($tocheck as $c)
		{
			if ($p==$c and $sentarray[$p]=='')
			{
				$error[]=$_POST[$p.'initvalue'];
			}
		}
	}
	return $error[1]==''?$sentarray:$error;	
}

}

function add($f)
{
global $errorindicator,$errorclass,$Javascript;
$tocheck=explode(',',','.$_POST['required']);

preg_match('/id="(.*?)"/i',$f,$i);
preg_match('/name="(.*?)"/i',$f,$n);
preg_match('/type="(.*?)"/i',$f,$t);
preg_match('/value="(.*?)"/i',$f,$iv);
$n=$n[1];$iv=$iv[1];$i=str_replace('_',' ',$i[1]);
if(preg_match('/<textarea/',$f))
{
	$v=$_POST[$n]==''?$i:$_POST[$n];
	$f=preg_replace('/<textarea(.*?)>(.*?)<\/textarea>/',
	'<textarea\\1>'.stripslashes(htmlentities($v)).'</textarea>',$f);
			if($Javascript){$f=preg_replace('/<textarea/','<textarea  onfocus="this.value=this.value==\''.$i.'\'?\'\':this.value"',$f);}
}	
if(preg_match('/<select/',$f))
{
	preg_match('/<select.*?>/',$f,$st);
	preg_match_all('/<option value="(.*?)">(.*?)<\/option>/',$f,$allopt);
	foreach ($allopt[0] as $k=>$a){
		if($_POST[$n]==$allopt[1][$k] || ($_POST[$n]=='' && $k==0)){
			$preg='/<option value="';
			$preg.=$allopt[1][$k].'">'.$allopt[2][$k].'<\/option>/si';
			$rep='<option selected="selected" value="';
			$rep.=$allopt[1][$k].'">'.$allopt[2][$k].'</option>';
			$f=preg_replace($preg,$rep,$f);
		}
	}
}else{
	switch ($t[1]){
		case 'text':
			$v=$_POST[$n]==''?'value="'.$i.'"':'value="'.stripslashes(htmlentities($_POST[$n])).'"';
			$f=preg_replace('/<input/','<input '.$v,$f);
			if($Javascript){$f=preg_replace('/<input/','<input onfocus="this.value=this.value==\''.$i.'\'?\'\':this.value"',$f);}
		break;
		case 'checkbox':
			$v=$_POST[$n]=='on'?' checked="checked"':'';
			$f=preg_replace('/<input/','<input'.$v,$f);
		break;
		case 'radio':
			$f=$_POST[$n]==''?$f:preg_replace('/checked.*?\s/','',$f);
			//$f=preg_replace('/checked.*?\s/','',$f);
			$v=$_POST[$n]==$iv?' checked="checked"':'';
			$f=preg_replace('/<input/','<input'.$v,$f);
		break;
	}
}
$f.='<input type="hidden" name="'.$n.'initvalue" value="'.$i.'" />';
if (array_search($n,$tocheck) and ($_POST[$n]=='' or $_POST[$n]==$i)){
		if($errorindicator!=''){$f=$errorindicator.$f;}
		if($errorclass!=''){$f=preg_replace('/name=/i','class="'.$errorclass.'" name=',$f);}
}
return $f;

}

function DisplayPage2()
{
$SESSION['POST_VARS'] = base64_encode(serialize($POST));
session_write_close();
header("location:abstract_page_2.php");
