how to display info from form on another page

maciek4

I want to gather information from the user and display it on another page.

In the file commit.php I have 2 fields

Product name:
Description:

<TR><TD ALIGN="right" VALIGN="middle" width="40%"> Product name:&nbsp;
</TD> 
 <TD ALIGN="right" valign="middle"><input name="name" size="27" type="text"></TD>
 </TR>
 <TR><TD ALIGN="right" VALIGN="middle">Description:&nbsp;</TD>
   <TD ALIGN="right">  <textarea name="desc" rows="5"></textarea>
   </TD>
   </TR>

And in the file add_new.php I want to display whatever text user wrote in those two fields Product name and description.

<?php

if (isset ($_POST['name']) || isset ($_POST['desc']))
   {
   echo'<form action="add_new.php" method="POST" name="submit">
   <TR><TD ALIGN="right" VALIGN="middle" width="40%"> Product name:&nbsp;
</TD> 
 <TD ALIGN="right" valign="middle"><input name="name" size="27" type="text" value="'.$_POST['name'].'"></TD>
 </TR>
 <TR><TD ALIGN="right" VALIGN="middle">Description:&nbsp;</TD>
   <TD ALIGN="right"><textarea name="desc" rows="5" value="'.$_POST['desc'].'"></textarea>
   </TD>
   </TR>
   </form>';
 }
 ?>

Unfortunatelly nothing is displayed althought there are no errors.

Recall your HTML:

<textarea name="desc" rows="5">'.$_POST['desc'].'</textarea>

Also, if you're going to be displaying this form even if one of the fields is not set (as stated in the if() test), then you ought to check to see if each field is set before you try to display its value.

First in your commit.php file you need to have a form similar to the one you have in add_new.php so the values can be submitted, it would have action="add_new.php" and it would need a submit button as well.

Then to display the values on the add_new.php page you need to use:
echo $_POST['name'];

For them to appear as the value within another form, you ought to be able to use something along the lines of:

This would be html outside of the PHP tags.
You also need to note Weed's comment on your incorrect <text area> tag.

<input name="name" size="27" type="text" value="<?PHP echo $_POST['name']; ?>"> doesnt work.

How do you mean it doesn't work ?

I don't think you've got the hang of forms, PHP isn't like javascript, it works on the server side and needs information submitted.

Let me give you a simple example:
form.html

<html><head></head><body>
<form action="form.php" method="POST" name="myform">
<input name="name" size="27" type="text">
<input name="submit" type="submit" value="submit">
</form></body></html>

Now we need form.php
This will have another form in which we want to insert the value entered by the user in the name box in form.html

<html><head></head><body>
<?PHP
$name=$_POST['name'];  // Takes the value passed by method POST in form.html
echo "<br><br>";
echo $name;  // echo out value of $name to check it was passed correctly
echo "<br><br>";
?>
<form action="form1.php" method="POST" name="myform1">
<input name="name" size="27" type="text" value="<?PHP echo $name; ?>">
<input name="submit" type="submit" value="submit">
</form></body></html>

You have it outside php in html, but I need to have it inside php code because its like this:

You enter add_new.php and you only have one link there "Add", you click on it and you get redirected to commit.php where you have two empty fields to fill out and a submit button. You fill out the fields and click "submit" and you get redirected back to add_new.php but this time apart from add link there is also your form with given data that you put into the 2 fields.

You can do it using exactly the same principles as I've used. Within commit.php you give your submit button a distinct name, say mysubmit, but design the form the same as I have done with form.html

In add_new.php you test for mysubmit being set:

if (!isset($_POST['mysubmit'])) {
Show a form with action="commit.php" and the Add button
}

elseif (isset($_POST['mysubmit'])) {
Show a form like I have in form.php
}
else {
echo "Panic";  // OK OK, but this case shouldn't be able to happen
}

I think many people here would actually do this with just one php file making use of PHP_SELF

It happened to be a different problem. Everything was ok except for the ahref in the submit button. I got rid of it and it is displaying ok. There is still problem with textarea because its not displaying the value.

Used that <textarea name="desc" rows="5">'.$_POST['desc'].'</textarea> and now its ok. Thanks
