How to remember selected values in all dropdowns?

General PHP Help
#1

Hello,

I have a plugin, which is calculating pregnancy weeks. But I want it to save the selected values after user has selected the submit button. Because now, when user clicks on submit button, all the values reset.

Here’s the code

[php]

function pregwcalc_add_page()
{
add_submenu_page(‘plugins.php’, ‘Pregnancy week calculator’, ‘Pregnancy week calculator’, 8, FILE, ‘pregwcalc_options’);
}

// pregwcalc_options() displays the page content for the pregwcalc Options submenu
function pregwcalc_options($widget_mode=false)
{
// Read in existing option value from database
$pregwcalc_table = stripslashes( get_option( ‘pregwcalc_table’ ) );

// See if the user has posted us some information
// If they did, this hidden field will be set to 'Y'
if( $_POST[ 'pcalc_update' ] == 'Y' ) 
{
    // Read their posted value
    $pregwcalc_table = $_POST[ 'pregwcalc_table' ];
    

    // Save the posted value in the database
    update_option( 'pregwcalc_table', $pregwcalc_table );
    
    // Put an options updated message on the screen
	?>
	<div class="updated"><p><strong><?php _e('Options saved.', 'pregwcalc_domain' ); ?></strong></p></div>
	<?php		
 }
	
	 // Now display the options editing screen
	    echo '<div class="wrap">';		
	    // header
	    echo "<h2>" . __( 'Pregnancy week calculator Options', 'pregwcalc_domain' ) . "</h2>";		
	    // options form		    
	    ?>
	
    <?php if(!$widget_mode):?>
	<form name="form1" method="post" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">
    <?php endif;?>    
	<input type="hidden" name="pcalc_update" value="Y">
	
	<p><?php _e("<p>You can use this calculator in two ways: as a standard Wordpress widget or by placing it in your post or page. For the latter please include the tag <b>[pregnancy-calculator]</b> in the content of your page or post and the calculator will appear there.</p>

I would be very pleased if you could help me with this problem. Since I have very little knowledge about the php, please write the solution as it would be for a noob :slight_smile:

Thanks!

#2

The solution would be to read up on sessions and use the session to hold your form data in variables.

#3

Could you please post the code and explain where to insert it? :slight_smile:

#4

:smiley: No

Maybe do some work yourself and try to do it, then when you cant do it then ask for help with your code after that.

#5

That’s kind from your side

#6

So what you want is someone to work for you for free ?
This is a help forum not a free freelance site.

We are happy to help you with your code but without any effort from you I do not think many would help you for free.

I have given you the starting place to look at.

#7

I have been researching for several days, and I understand what should I do in my case. But I have no idea where I should look in posted code to start changing something.

Moreover I cant afford spending months reading and analyzing php coding, because I wont need it in my website. So I am asking people, who understand to help me and save me some time, so I can move further and expand my website!
