PHP - Drop Down Menu From Single Item
I've followed a few tutorials, as I've never touched drop down before (more of a conventional navbar guy ). But none are dropping the nested list :-\. I even took the code from one, no changes made, and it still didn't drop the menu
This is as far as I got on this tutorial (http://line25.com/tu...s-dropdown-menu) before coming here
#topbar-navigation
{
width: 101%;
margin: 0 auto;
;
margin-top: -8px;
height: 56px;
background: #ffffff;
display: inline-block;
text-align: center;
min-width: 1100px;

-moz-box-shadow: 0 1px 8px 0px #b5b5b5;
box-shadow: 0 1px 8px 0px #b5b5b5;
}
#topbar-navigation ul
{
display: inline-table;
list-style: none;
position: absolute;
margin-left: auto;
margin-right: auto;
margin-top: 20px;
top: 0;

right: 0;
}
#topbar-navigation ul:after

Similar TutorialsHi all,
I am trying to validate all required fields in my contact form using php. However I am unable to retain what was selected in my country dropdown list after it is selected and submitted if the form had errror while validating. I want the form to retain the value that was selected by the user to stay in the form so that users can make necessary changes and resubmit the form all other values stay in the form except the country dropdown. Please help Below is the code.

Edited by Ch0cu3r, 15 July 2014 - 03:37 PM. Reformatted post hello, i have this simple problem, how can i point to an item in a menu so that it shows the correct page i'm currently visiting? for example, i have this menu : Code: [Select] <div class="submenu"> <div class="submenu-head">Products</div> <ul> <li class="first-item current"> <a tabindex="1" class="first-item current" href="index.php">Products</a> </li> <li> <a tabindex="1" href="add_product.php"> Add new Product </a> </li> </ul> </div> where class="first-item current" points to the current page i'm visiting (i.e Products is highlited) so when i visit another page (add_product.php) i want to do this Code: [Select] <div class="submenu"> <div class="submenu-head">Products</div> <ul> <li > <a tabindex="1" href="index.php">Products</a> </li> <li class="first-item current"> <a tabindex="1" class="first-item current" href="add_product.php"> Add new Product </a> </li> </ul> </div> the usual way i solve this problem is by using a switch statement Code: [Select] switch($header_title) { case "index": echo "<div class="submenu"> <div class="submenu-head">Products</div> <ul> <li class="first-item current"> <a tabindex="1" class="first-item current" href="index.php">Products</a> </li> <li> <a tabindex="1" href="add_product.php"> Add new Product </a> </li> </ul> </div>"; break; switch "add_product": echo "<div class="submenu"> <div class="submenu-head">Products</div> <ul> <li > <a tabindex="1" href="index.php">Products</a> </li> <li class="first-item current"> <a tabindex="1" class="first-item current" href="add_product.php"> Add new Product </a> </li> </ul> </div>"; break} but this is not very efficient, cause if have 10 menu links i would have to write 10 cases so how can u do this without having to write all those cases, like maybe use a function instead?? Hey Im always trying to remove code and cut corners to reduce work in the long run, soIim wondering how I could link my menu bar from say a template to ALL my php pages for my site so I don't have to write/change links on every page when I need to. Thanks I have a script that seems to work well to insert a bookmark into a users database when he/she is logged into the system but I am having a hard time figuring out how I would go about making a work-a-round for having an item selected before being logged in, and inserted after they have logged in or registered. For example, I would like a user to be able to select an Item to add to bookmark whether that user is logged in/registered or not and if they are not, they would be greeted with a login/registration form and after successful login the add bookmark script would be initiated on the item previously selected. What I've got this far: Simple form to add bookmark: <form name="bm_table" action="add_bms.php" method="post"> <input type="text" name="new_url" value="http://" /> <input type="submit" value="Add Bookmark"/> </form> Then I have the add bookmark script: BEGIN php $new_url = $_POST['new_url']; try { check_valid_user(); //cannot get past this part since it ends the script....code below if (!filled_out($_POST)) { throw new Exception('Form not completely filled out.'); } // check URL format if (strstr($new_url, 'http://') === false) { $new_url = 'http://'.$new_url; } // check URL is valid if (!(@fopen($new_url, 'r'))) { throw new Exception('Not a valid URL.'); } // try to add bm add_bm($new_url); echo 'Bookmark added.'; // get the bookmarks this user has saved if ($url_array = get_user_urls($_SESSION['valid_user'])) { display_user_urls($url_array); } } catch (Exception $e) { echo $e->getMessage(); } END php Checking valid user - the portion I cannot get past in the above script: function check_valid_user() { // see if somebody is logged in and notify them if not if (isset($_SESSION['valid_user'])) { echo "Logged in as ".$_SESSION['valid_user'].".<br />"; } else { // they are not logged in do_html_heading('Problem:'); echo 'You are not logged in.<br />'; do_html_url('login.php', 'Login'); do_html_footer(); exit; } } How would I go about modifying the script so that a user could fill in the form (later it would be a link...obviously they probably wouldn't be filling in a form that is log-in specific - but same concept I think) Thanks in advance for the help! tec4 Hi there, I think this is a big question but I'd appretiate any help you can provide!! I have a list of items and subitems in a table that looks like this: id parent_id title 1 0 House Chores 2 1 Take Out Trash 3 1 Clean Room 4 0 Grocery List 5 4 Eggs 6 4 Produce 7 6 Lettuce 8 6 Tomato 9 4 Milk I want to display it like this: (+) House Chores: > Take Out Trash > Clean Room (+) Grocery List: > Eggs (+) Produce > Letutce > Tomato > Milk So basically each entry in the table has an unique id and also a parent id if it's nested inside another item. I "sort of" got it figured out in one way, but it doesnt really allow for nested subgroups. I'd like to know how would y'all PHP freaks to this Also taking suggestions for the javascript code to expand/collapse the tree !! Thank you! PHP script return 20 UL LIST values like, < ul >
A < /ul > How to display UL LIST into row wise 5 columns like
A B C D Hi, I've been scratching my head for a while now about how to do this, I'm relatively new to php and mysql and perhaps foolishly taking on creating a user area for a website. I have everything else working, all of my register account functions and confirmations and all of the login scripts etc. I have created a profile page which returns various information to the user (this bit works fine) and I've got some nice show/hide toggles running with some javascript/css but my intention is to allow the user to change thier information (e-mail address, contact phone number and also whether they are subscribed to the e-mail list), it also displays any support tickets or messages. So after the long intro, here's what I'm struggling with... I have a form in a visibility toggled <div> which submits a 'change_email' script, so a user wants to change their e-mail, clicks on change, the <div> appears, they bang in the new e-mail and hit submit. My php script appears to work (because it doesn't throw up any errors), until you realise that actually it's not updated the record in the db... I'm using mysql_query("UPDATE users SET email='$new_email' WHERE username='$user'"); Do I need to setup variables for all of the information in the db (name, username, password, email, contno etc etc) and include them in the command to get it to work or should that just pick the correct record and then update it? If that is the case is there a way I can include 'blank' variables so I don't have to set them all up... e.g. mysql_query("UPDATE users SET user='',password='',email='$new_email', etc WHERE username='$user'"); Many thanks in anticipation Hi I have a temporary web page with a drop down menu. Problem is to get rid of the gap on the drop down menus. Any help please

I am using a combination of PHP and AJAX to create two drop down menus on a HTML form. The data is being pulled from a mySQL database with the options available in the second drop down dependent on the value selected in the first. The initial drop down menu called 'detectors' and the behaviours for the second drop down menu, 'searchheads' are created with the following AJAX code: Code: [Select] Function AjaxFunction(detectorid) { var httpxml; try { // Firefox, Opera 8.0+, Safari httpxml=new XMLHttpRequest(); } catch (e) { // Internet Explorer try { httpxml=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { httpxml=new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { alert("Your browser does not support AJAX!"); return false; } } } function stateck() { if(httpxml.readyState==4) { var myarray=eval(httpxml.responseText); // Before adding new we must remove previously loaded elements for(j=document.addfindstolocation.searchheads.options.length-1;j>=0;j--) { document.addfindstolocation.searchheads.remove(j); } for (i=0;i<myarray.length;i++) { var optn = document.createElement("OPTION"); optn.text = myarray[i]; optn.value = myarray[i]; document.addfindstolocation.searchheads.options.add(optn); } } } var url="searchheaddetails.php"; url=url+"?detectorid="+detectorid; url=url+"&sid="+Math.random(); httpxml.onreadystatechange=stateck; httpxml.open("GET",url,true); httpxml.send(null); } The following code is the file 'searchheaddetails.php' (as highlighted above) which populates the second drop down menu. Code: [Select] <? $detectorid=$_GET['detectorid']; require "config.php"; $q=mysql_query("SELECT * FROM searchheads WHERE detectorid='$detectorid' ORDER BY 'searchheadname' ASC"); echo mysql_error(); $myarray=array(); $str=""; while($nt=mysql_fetch_array($q)){ $str=$str . "\"$nt[searchheadname]\","; } $str=substr($str,0,(strLen($str)-1)); // Removing the last char , from the string echo "new Array($str)"; ?> And this is the section of my form that pulls together the two drop down menus. Code: [Select] <form name="addfindstolocation" method="post" id="addfindstolocation"> <div align="left"> <select name=detectors id="detectorid" onchange="AjaxFunction(this.value);"> <option value=''>Select One</option> <? require "phpfile.php";// connection to database $q=mysql_query("SELECT * from detectors WHERE userid='1'ORDER BY 'detectorname' ASC"); while($n=mysql_fetch_array($q)){ echo "<option value=$n[detectorid]>$n[detectorname]</option>"; } ?> </select> </div> </div> <p align="left"> <label></label> <label>Search Head Used</label></p> <div> <div align="left"> <select name=searchheads id="searchheadid"> </select> </div> The drop down menus work fine, but I'm having a little difficulty with the data that is being saved. For the 'detectors' drop down menu the data being saved upon a selection being made is the 'id' pertient to the relevant detector e.g. 'Detector1' is selected and the 'id' value of '1' is saved which is exactly what I want. However when it comes to the second drop down menu, the value saved is the text value that the user selects, rather than the 'id'. e.g. 'Deep Search Head ' rather than an 'id' of '1'. Could someone perhaps tell me please what I need to change so that the 'id' value is saved rather than the text value. If it helps, the coding is taken from the following http://www.plus2net.com/php_tutorial/ajax_drop_down_list.php. Many thanks and kind regards. Chris helo i a newbie in php. i need some help regarding my system. i want my data from database to display in drop down menu form.anyone have idea how to do that? i really need some help. i have search all over and couldn't find any solution. any suggestions would be helpful I did search this up but all of them were lists.
I want to make a menu drop down like so....
Non-clicked...
Clicked...
The grey boxes would be images (unless it is easier to code them).
I am a complete noob so please don't use technical terms
Thanks
Okay, so, here's the scenario. I have a form that is editing an item that is already in the database. The text fields fill in just fine with that info. However, the drop down menus don't retrieve that info, rather resorting to the defaults, which can be a problem if you don't remember what you originally had. Is there anyway to make the dropdown menus pull the info from the table and use that rather than resorting back to the default? I tried using this: Code: [Select] <tr><td width="20%">Bonus:</td><td><select name="bonus" value="{{bonus}}"> <option value="Attack" {{bonus1select}}>Add to the attack power of weapon</option> <option value="Defense" {{bonus2select}}>Add to the defensive power of armor</option> <option value="None" {{bonus3select}}>No effect</option> </select><br /></td></tr> So, it's obvious the "value" portion not working. Any help would be great!! Hi, i know this is probably very basic but i have been banging my head and looking for tuts. i have built a mysql php dropdown menu. all displays fine. now, how do i get the menu to actualy take me to a new url? the new url should be www.mysite.com/"menu selection" Code: [Select] <? include_once 'includes/db.php'; $result = mysql_query("select * from crimerate WHERE DISTRICT = 'Limpopo'", $con); if (!$result) { die('Invalid query: ' . mysql_error()); } $options=""; while ($row=mysql_fetch_array($result)) { $id=$row["id"]; $crime=$row["CRIME"]; $options.="<OPTION VALUE=\"$id\">$crime</option>"; } ?> <SELECT NAME=crime> <OPTION VALUE=0>Choose <?=$options?> </SELECT> I'm trying to code a drop-down menu that has four options; one for pie,exp, root 3, and the golden ratio.(all math values) Beside the drop-down menu, there is an option for user-inputted data, they must input only positive numbers. I must take there selected drop-down menu option and times it by the user inputted number. I'm not sure how to check which option the user chose.
<form id="s" method="post"> </select> <input type="submit" name="Submit" value="Send"> Everything That ive tried has failed I have lots of tables for my products could i use the table name for a drop down menu? or is it not safe Thanks for any help I'm having a problem with populating a second drop down menu that needs to be identical to the first from a mysql database. I have about 20 items in the DB & I only want to show the first 9. My code is: Code: [Select] <select name="a_type" style="width: 175px;"> <option value="" selected="selected"> None selected</option> <?php $i=1; while (($_produce = mysql_fetch_array($result_produce)) && ($i <=9 )) { $produce_type=$_produce["type"]; $produce_id=$_produce["id"]; $i++; ?> <option value="<?php echo $produce_id; ?>"><?php echo $produce_id; ?> - <?php echo $produce_type; ?> </option> <?php } ?> </select> That works fine in my first drop down menu but the second drop down menu with the same exact code will show items starting at 11 & higher instead of 1 to 9. I haven't tried closing the DB & the reopening it which I assume would work but there are a lot of other variables & things I'd have to check to make sure they don't get effected so I'd rather not. Is there a simple way to solve this? Hello! This is my first post here. I'm usually do programming in Ruby (Rails) but for a special occasion I need PHP. So hi PHP people! I come in peace My question is quite simple. How do you make a drop down menu? Most preferably with database populated fields in it. In the Rails community, this really helped me make these menus in Rails: http://www.kahfei.com/?p=23 Could someone briefly write something like that too? (The place holders) Orrr you guys can just explain how to do it. The ones I found on the internet were quite confusing and not explained enough. Help anyone? Thank you Hey guys im looking to do a drop down menu which is pretty basic however, in this drop down menu it uses an array of 4 values eg Orange, Apples, Bananas, Strawberry's. For this menu if a user has previously chosen an Orange which is stored on the db then then when the drop down menu is loaded it should move Orange to the top of the list, the same applies for the other values. How could I do this? I know how to do the select statement and place the values in an array. from there I dont know quite how to approach it. () Thank you. |
