Retain what was inputted

johnseito · July 9, 2008

Hello everyone,

I created a simple userform to test. What I wanted to do is have the user input a field,

and then click on the submitted button once the submitted button is click

the page refresh and still retain what the user input (it is not lost).

I know that to do this, we have to use the isset function, which I did, but it didn't work.

Here are my codes, please provide some suggestion and code examples.

<html>
<head>
<title></title>
</head>

<body>

<form method ="post" action="">   

<table border = 1 > 

<tr> 
<td>


		<?php session_start();  $firstname = (isset($_POST['firstname'])); 
		$lastname = (isset($_POST[lastname]));?>
  First Name:      	<input name="firstname" type="text" value='<?php       $firstname  ?>'/></td>
</td>
</tr>


<tr> 
<td>
  Last Name:      	<input name="lastname" type="text" value="' . $lastname . '"/></td>
</td>
</tr>

<tr> 
<td>         
       <input name="submit" type="submit" value="Enter the information">

</tr> 
</td>

thanks,

First Name:      	<input name="firstname" type="text" value='<?php echo $firstname;  ?>'></td>
</td>
</tr>


<tr> 
<td>
  Last Name:      	<input name="lastname" type="text" value='<?php echo $lastname; ?>'></td>
</td>
</tr>

Just missing the echo statements really. Also need the php tags in each area as I edited.

That's because when you're using ISSET, you're storing the value 1 (as in, it is set), not the variable itself. You need remove the ISSET function.

The whole code would be:

<html>
<head>
<title></title>
</head>

<body>
<form method ="post" action="">   

<table border = 1 > 

<tr> 
<td>

  First Name:      	<input name="firstname" type="text" value="<?php echo $_POST['firstname'];  ?>" /></td>
</td>
</tr>


<tr> 
<td>
  Last Name:      	<input name="lastname" type="text" value="<?php echo $_POST['lastname']; ?>" /></td>
</td>
</tr>

<tr> 
<td><input name="submit" type="submit" value="Enter the information">

</tr> 
</td>

Isset() just returns 1(True) 0(false). So that's what you were storing in your field values.

If your goal with the ISSET function is to ensure the form was used, you actually want to check that the submit button "is set".

You would use

<?php

If (isset($_POST['submit'])) {

// the actions taken on the information from the form

}

?>

Ok, that works.

So how would you do this for a option field, where user selects one and

code retain the one selected.

</td>	 	<td><select name="gender">
			<option value=""  selected>- Select One -</option>
				<option value="Male" >Male</option>
				<option value="Female" >Female</option></select><br></td>

I created an array to loop user's selection, but when the user select an item and click on the button it retains

only the item (on the list) after.

does someone know why, I assume it that when you select one item, then when you click the submit button

the for loop runs again and select the next item on the list, retaining the wrong item.

<tr><!--I LIVE IN----------->
<td align="right">    <?php print"$Live";   
?>

       </td> 
			<td><select name="country">
                     

         <option value=""<?php if ($_POST['country'] == '') echo ' selected="selected"'; ?>>- Select One -</option>

}

Try replacing your foreach loop with this:

foreach ($countries as $value) {

if($sel == ""){
$sel = ($_POST['country'] == $value) ? ' selected="selected' : '';
}

}

print'<option value="'.$value.'"'.$sel.'>'.  $value. '</option>\n';

johnseito · July 12, 2008

print'<option value="'.$value.'"'.$sel.'>'.&#160; $value. '</option>\n';

something is wrong with this code, syntax, expected "&"

JasonLewis · July 12, 2008

print '<option value="'.$value.'"'.$sel.'>'.$value. '</option>\n';

My bad, must have happened when I coppied...

johnseito · July 12, 2008

I just tried, that code didn't work.

It doesn't retain what was selected but have "select one" in the field

after selecting an option and clicking on the submit button.

JasonLewis · July 12, 2008

Try this... Sorry I probably made it worse for you before.

foreach ($countries as $value) {

$sel = ($_POST['country'] == $value) ? "'selected'='selected'" : "";
echo "<option value='{$value}' {$sel}>{$value}</option>";

}

I'm kind of sleepy.
