PHP - How To 'orden' Dropdown Menu Alphabetically

Trying to find an answer for this question he http://stackoverflow.com/questions/7547960/sorting-displaying-by-numeric-and-then-alphabetically

If any of you guys can't help that would be great

Hi

Sorry if this is the wrong place for this but I'm totally stumped here and I know its a basic question but I'm very new to php and I need help :-)

Basically all i would like to do is list the files and folders in the following directory alphabetically, I know i need to put them in an array etc but I don't know how and would really appreciate some help! So any help would be very gratefully received.

Here's my code so far:

<?php

$sub = ($_GET['dir']);
if (strstr($sub, "..")) {$sub = "";}
$path = '../media/Documents';
$path = $path . "$sub";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
if(substr($file,0,1) != ".") {
if (substr($file, -4, -3) =="."){
echo "<font size=2 face=\"Arial, Helvetica, sans-serif\">$i.
$file <br />";
}else{
echo "<font size=2 face=\"Arial, Helvetica, sans-serif\">$i. <a
href='?dir=$sub/$file'>$file</a><br />";
}

$i++;
}
}
closedir($dh);

?>

Many thanks in advance!

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!!

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

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        

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>

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

Using unordered list, <ul>
Reading from XML file,
Taking menu name from database,

Is there other system to make dropdown navigation menu?
Which is the best way to make dropdown navigation menu?
I also want to show the sitemap of navigation.How can it be done?

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

I'm not sure what to search for or if this can be done...

Let's say I have a mysql table named "genre". Now I have "Male" and "Female" in a dropdown menu like this in a form:

<select name="genre">
  <option>Male</option>
  <option>Female</option>
</select>

How would you display, for example, the option Female in a update.php file if that's the genre stored in the mysql database when you fetch the results?

Hi All,
