PHP - Validating Selection In Dropdown Menu

So i have a <drop down> menu, and a <nav> menu on my left side of the page. I have a problem when i click at the first column of my drop down menu and it explores submenu, the submenu mixes with the nav menu that is under the drop down menu on the left. i could solve it with margin-top of the nav menu but i don't like the empty space beetwen them. I tried with putting overflow:visible; in CSS of my dropdown menu but it is still the same. drop down menu is seen but there is stil seen nav menu under and they are mixed. So basicly i want my dropdown menu to be priority,  so when i clicks on my first column (only first column is problem because there under is nav menu the other are open nice) it will explore submenu and the part of nav menu that covers the submenu will be hidden.   Here is the screen shot:     Here is the code of head <dropdown> menu if someone finds the problem.

My problem is when the entries in the form are validated and some fields with incorrect entries are found the fields filled out stay on the re-load of the form, all of them except the US States drop down menu which reverts back to Alabama every time.

I would like to see that the user selection stays in place even after a re-load of the form. and with my limited experience I am having an issue trying to figure this out for a school project.

Any help at all would be greatly appreciated, like what variables to create/call on and where exactly I insert this code.

Much appreciated.

here is the display code:
 

<?php
/* Program name: exercise_4_form.inc
* Description: Defines a form that collects a user's
* name and mailing address.
*/
$rows = array( "first_name" => "First Name (optional)",
"last_name" => "Last Name",
"phone" => "Phone Number",
"city" => "City",
"state" => "State",
"address" => "Address",
"zip_code" => "ZIP Code",
"e_mail" => "E-Mail");

$states_list = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",
'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",
'DE'=>"Delaware",'DC'=>"District Of Columbia",'FL'=>"Florida",'GA'=>"Georgia",
'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa",

$submit = "Submit mailing information";

<?php

foreach($rows as $field => $label)

if($field == "state")
{

}

echo "<div id='submit'>

Hi i have a online/offline script that works great no issues at all. In order to change the html, php file to display when offline I need to point it to that file via input field. What i would like is to change the input filed and have a dropdown that list all the folders and subfolders within the the directory where all the templates are located. I have found a php snippet on the forum that does exactly what i want. The issue is now is to remove the input filed in the script and insert the snippet found here and thats where the issue comes. I'm hoping some guru here can easily help me out . please see below for the code

Hi all, I was wondering if someone knows a clean way to make a dropdown menu using just php and html with the following functionality. If someone selects a value from the dropdown options it should be visible on refresh.
So in case a have a dropdown menu with: oranges, apples, grapes and someone selects grapes and submits it, grapes should be selected.

I have made someonthing but it looks redundant. I think there should be something with a foreach loop or something but i can't figure it out yet.

Thanks in advance,
cheers!!

I think after a lot of trouble I've finally managed to get my hierarchical php driven hierarchical dropdown menu working. I now have 1 problem with it which I simply can't figure out. Rather than explain this I think a picture is worth a thousand words so here's the script in action:-

http://www.coolvisiontest.com/garyssite/rhrvouchers/menu4.php

If you notice in that example when you hover over categories then level1a then level2a the menu's and their children appear 1 at a time as they should. However if you hover over level1a then level2b then all at once all of the child categories of 2b and all of their child catagories and their child categories etc appear at once rather than one at a time. You should have to hover over level3e to see level4a and you should have to hover over level4a to see level5a etc.

The code I have is a combination of 2 sets of code I came across to be honest so I'm having trouble figuring it out.


At the moment I only have 3 problems with it:-

1. I only want subcategories to be shown when their parent category is hovered over as explained above
2. I only want the bottom level of categories to act as links e.g. levels 2c 3a 3b 3c 3d and 5a would act as links in this example as they are the last of all the children, the rest of the categories should be plain text. I'm not sure if this is achievable though as I think links are required for the hover functionality.
3. I want some way of indicating to the user that a category has children perhaps by including a little right arrow or plus sign and of course this should only be included for the categories that have children and not the others.

Can anyone help me out with these three things please? Here's my code so far:-



<?php

$link = mysqli_connect('localhost','','');
mysqli_select_db($link,'');

$query = mysqli_query($link,'SELECT * FROM nested_categories');
while ( $row = mysqli_fetch_assoc($query) ){        
$menu_array[$row['id']] = array('id' => $row['id'],'name' => $row['name'],'parent' => $row['parent_id']);
}

function generate_menu($parent){        
$has_childs = false;        

global $menu_array;        

foreach($menu_array as $key => $value){                
if ($value['parent'] == $parent){ 
                              
if ($has_childs === false){                                

$has_childs = true;                                
echo '<ul>';                        
}                        

echo '<li><a href="menu4.php?id='.$value['id'].'">'.$value['name'].'</a>';                        
generate_menu($key);                        

echo '</li>';                
}        
}        
if ($has_childs === true) echo '</ul>';
}

?>

<div id="menu">
<ul>

<li><h2>categories</h2>

<?php generate_menu(0); ?>

</li>

</ul>

</div>

Hello,   I'm new to php, I don't really have much experience, just have used it in combination with dreamweaver. I'm tackling a new problem now.   Basically, it's about a dropdown menu with pre-defined values. There are multiple dropdowns, having different value choices. People are supposed to be able to select more than one option and then search for the results. these should then be generated according to the selected values, or if no value is selected, ALL is shown.   When the user clicks on search, the values create a msql query that will then be executed and the results shown on the page.   I've been searching high and low for code ideas, but see different stuff everywhere I look, and none of the code seems to be what i want. Some people are using Javascript, some Ajax, or PHP. ideally, I want to use just php and sql   Can someone point me in the right direction on how to tackle this problem, or maybe someone has some code ideas?   Thanks in advance.   Mio        

Hi, I don't know if this is the right place, but I used a code for a dropdown menu witch works fine on the website (geloven.eu/ABK2021) who uses PHP 7.2.24, but the dropdown does NOT work on another site bijbelkamp.eu/ABK2021 who uses PHP 7.3.28.

The index page just includes the menu.php (here menu.txt) and the css file bootstrap21.css (here bootstrap21.txt).

Can this be some coding issue or does this have nothing to do with the code?

bootstrap21.txt menu.txt

Hi, I'm trying to get data from one field in a table (database). But I get undesirable result: Here is my code ->

<?php
$result2 = mysql_query("SELECT DISTINCT theme FROM  mytable ")
               or die(mysql_error());
         
            
            while($row2 = mysql_fetch_array( $result2 ))
               {
?>
                  <form method="post" action='<?php echo $_SERVER["PHP_SELF"]; ?>'>

                     <select name='themes'">
<?php
                   
                  $arr= array($row2['theme']);
      
                  foreach($row2 as $value)
                  {
                     echo "<option value='$value'><b>". $value."</b> </option><br> ";
                     
                  }
                  
               }
?>

The attached image file show the result that I don't wont. (It's not a dropdown).
Is there anyone who may help me, I spent a lot of time to find out but I can't.

Thanks a lot for your help

Some forum users here gave me great help yesterday in working with dropdown menus. In fact, I need quite a few of these dropdown menus in several forms over several pages, so I created several simple arrays and made a function to create the dropdowns.

Here's one of my arrays:

Code: [Select]
<?php
$instruments = array(
'Bassoon', 'Cello', 'Clarinet', 'Double Bass', 'Flute', 'French Horn', 'Oboe', 'Percussion', 'Trombone', 'Trumpet', 'Tuba', 'Viola', 'Violin', 'Other'
);

Here's my function:

Code: [Select]
<?php
function create_dropdown($array_name, $array_item) {
  echo "<select name='$array_item'>\n";
  echo "<option value='select'>Select&hellip;</option>\n";
  foreach( $array_name as $v ) {
    echo "<option value='$v'>" . $v . "</option>\n";
  }
  echo "</select>\n";
}
... and anywhere I need a dropdown menu, I'm calling it like this:

Code: [Select]
<?php
create_dropdown($instruments, 'instrument');
The dropdown menus, however (in some fairly detailed forms for my local youth orchestra's site), need to be sticky.

How can I modify my function, above, so that the selected value will be retained if there are other form submission errors when the form is submitted?

I have tried endlessly today but to no avail... If you can help while I still have some hair left, I'd be greatly appreciative.

Hello I am having a trouble with creating page that will search records from database using dropdown menu, when I select a category, for example By: Gender and after clicking the Submit button, there is no records displays but when I select By: ALL, the records displays. What's wrong with my code? I'm sorry I'm fairly new to PHP. Here is my code:


Code: [Select]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
