PHP - Moved: Dropdown Menu Onchange Help

Hey guys
I wasnt sure if this is a php topic or java script
im trying to make my drop down menu's activate onchange. what confuses me is how do I make php know that the java script is being run. Or have the java script trip my php code.

To know a button has been pressed i use "if (isset['_POST'])"


 echo '<select name="siege_list" id="siege_list">';

foreach($name as $key => $value) {        

echo '<option value="' . $value['name'] . '" ' . ($value['name'] == $current1
['name'] ? 'selected="selected"' : '') . '> ' . $value['name'] . '</options>';
}                           
echo '</select><input type="submit" id="siege_planet" onchange="this.form.submit()">';

Hello:

I have a SELECT dropdown menu that works like this:
Code: [Select]
<?php

$states_arr = 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",  'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming");
    
    function showOptionsDrop($array){
        $string = '';
        foreach($array as $k => $v){
            $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n";
        }
        return $string;
    }
?>

<form>

<select name="states">
    <option value="0">Choose a state</option>
    <?php echo showOptionsDrop($states_arr); ?>
</select>


</form>

I would like to show all the towns/zipcodes for each individual state with an "onchange" from the SELECT menu.

The table is called "zip_codes" and the City/Zip Codes are called "city" and "zip"

What I would like to do is display them as links, so a user can click into each town and either create a new entry (a restaurant) or update an existing entry.

What would be the best approach for this?

I appreciate the help.

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.

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

online/offline code ( input filed i would like to replace with dropdown selector <input type="text" name="txttemplate" value="%s" id="txttemplate" />)

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>




And the Css:-


#menu {
width: 100%;
background: #eee;
float: left;
}
#menu ul {
list-style: none;
margin: 0;
padding: 0;
width: 12em;
float: left;
}


#menu a, #menu h2 {
font: bold 11px/16px arial, helvetica, sans-serif;
display: block;
border-width: 1px;
border-style: solid;
border-color: #ccc #888 #555 #bbb;
margin: 0;
padding: 2px 3px;
}

#menu h2 {
color: #fff;
background: #000;
text-transform: uppercase;
}

#menu a {
color: #000;
background: #efefef;
text-decoration: none;
}

#menu a:hover {
color: #a00;
background: #fff;
}



#menu li {position: relative;}

#menu ul ul {
position: absolute;
z-index: 500;
}

#menu ul ul ul {
top: 0;
left: 100%;
}




div#menu ul ul,
div#menu ul li:hover ul ul,
div#menu ul ul li:hover ul ul
{display: none;}

div#menu ul li:hover ul,
div#menu ul ul li:hover ul,
div#menu ul ul ul li:hover ul
{display: block;}

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        

how do i this? i have no idea....i need to incorporate it on an html form
pleas help?

i will get the data from this line and must be able to select one from the dropdown and get the id/name from the one selected

[COLOR="Red"]$supplier_names = LpmAdnetworkPeer::getByName($catcher_id);[/COLOR]

thank you

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

I want make the following,
(I have already a database with three tables (Countries, Timeline and Category)).

1: list of countries (drop down menu 1), Timeline of the countries history (drop down 2) and Category (drop down 3).
2: The selected values of the drop down menus must show take the information from the database.

Can any one help me with the coding?

I'm attempting to create a dropdown hover menu by following the instructions on the Suckerfish site. The list that is supposed to dropdown simply stays visible all the time. Is there anything in the code that seems to be the apparent cause of the problem? You will be able to tell that I'm new to PHP. Any suggestions would be appreciated.

The following is my CSS and PHP code:

CSS:

Code: [Select]
#nav, #nav ul{
padding: 0;
margin: 0;
list-style: none;
}

#nav a{
display: block;
width: 10em;
}

#nav li{
float: left;
width: 10em;
}

#nav li ul{
position: absolute;
width: 10em;
left: -999em;
}

#nav li: hover ul{
left: auto;
}

#nav li:hover ul, #nav li.sfhover ul{
left: auto;
}

PHP/JavaScript:



Code: [Select]
function draw_app_menu() {
    // draw the application menu
?>
    <!-- left - background-color: #cdeb8b - lime -->
[color=blue]<script type="text/javascript">
shHover = function() {
  var sfEls = document.getElementByID("nav").getElementsByTagName("LI");
  for (var i=0; i<sfEls.length;i++) {
      sfEls[i].onmouseover=function() {
        this.className+=" sfhover";
      }
      sfEls[i].onmouseout=function() {
        this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
      }
    }
  }
 
  if (window.attachEvent) window.attachEvent("onload",sfhover);
