preview pages

[purpleI]

Hi all,

I am creating a website where the user can upload an advert. However, i want to add a preview function (similar to the one on this website when you create a new thread).

Currently, i have created a form which passes data on to a confirmation page:

<form action="confirm.php" method="POST">
              <input type = "text", name="make">
              <input type = "text", name="model">

I would then like confirm.php to display the advert preview. Below the display i would like to include the same form allowing updates to be made. Any suggestions/guidance on how this can be done?

My first thoughts are to post the data back to the same page. However, how do you get the form to hold the data input by the user?

e.g.

 <input type = "text", name="make" value=<?$make?>> where $make = $make=$_POST['make'];

does not work.

Hello,
how about this?

 <input type = "text" name="make" value="<?php echo htmlspecialchars($make) ; ?>"> 
in a textfield you should not use    , 

if the user add to the field ' " \ or other special characters, they will kill your html code, that's why you need to use a function to change them into quoted characters.

-form to hold the data input by the user?-

i use functions to make form elements , and rewrite the posted values.
Its not useful if you need one or two fields, but useful if you make about 10+ 🙂
You can combine the required fields as you wish. It collects the error messages in a global array:
$errors_code
I've made a little example of how to use it.

Hello,

<?php
	function submit()
	{
		/* Lets print the submit button */
		print ' <input type="submit" name="Submit" value="Submit"><br />'."\r";
	}

function make_tf($var,$label,$required)
{
	global $error_code;
	/* Lets test, if the user posted the form with the variable name: $var*/
	if(!empty($_POST[$var]))
		$value=htmlspecialchars(stripslashes($_POST[$var]));   /* if yes, lets create a variable to the textfield's value, and don't forget to convert special html characters with htmlspecialchars */
	else
	{
		$value="";   // if the user did not fill that field, lets add an empty as a value
		if($required==1)
		$error_code[]=$label;
	}
	if($label!="")
		print $label.": ";   //if you don't want to add a label to that textfield

	/*     Lets print a textfield with a variable name $var and a default value with $value */
	if(strstr($var,"password"))
	{
		$type="password";
		$value="";  //do not add a default values into password fields...
	}
	else
		$type="text";
	if($required==1)
		print "(*) ";
	print ' <input type = "'.$type.'" name="'.$var.'" value="'.$value.'"><br />'."\r";

}

function errors()
{
	global $error_code;

	if(isset($error_code))
	{
		foreach ($error_code AS $rows)
			print "<b>$rows</b> must have been filled!<br />\r";
		return false;
	}
	else
		return true;
}

?>
<form action="index.php" method="post">
<?php
	make_tf("make","Make",1);
	make_tf("model","Model",0);
	make_tf("username","Username",1);
	make_tf("password1","Your first password",1);
	make_tf("password2","Your second password",1);
	submit();
/* with error()   function you can print all the errors connected with this form. It returns false if the user missed some fields, and return true if evrything is OK*/
	if(errors()==true)
		print "The form could send now, all required fields have been filled";
	else
		print "Please check the missing fields";

?>
</form>
