I need help on this please. I want to show only those whose links are not empty. Meaning if there are empty links from the database, that particular list item for where there is an empty link should not show
<?php
foreach ($stmtsocials as $socials) { ?>
<ul class="social-profile social-profile-styled">
<li><i class="facebook-bg"></i></li>
<li><i class="lab la-twitter"></i></li>
<li><i class="lab la-instagram"></i></li>
</ul>
<?php } ?>
One option is that you can do like following using if condition.
<?php
foreach ($stmtsocials as $socials) { ?>
<ul class="social-profile social-profile-styled">
<?php if (!empty($socials['LT_SOC_FB'])){?>
<li><i class="facebook-bg"></i></li>
<?php }?>
<?php if (!empty($socials['LT_SOC_TWITTER'])){?>
<li><i class="lab la-twitter"></i></li>
<?php }?>
<?php if(!empty($socials['LT_SOC_IG'])){?>
<li><i class="lab la-instagram"></i></li>
<?php }?>
</ul>
<?php } ?>
And 2nd option is you can select only those rows which are not empty using query. Then you don't need for if condtion

I am currently working on a tour website, where the number of destinations is available for the user. A Login user can like any destination which will be added to his favorites destination section. I have done this task successfully. But after liked the destination the like button appears multiple times or equal to the number of likes have the user done. Maybe I am wrong in my logic here is my code. The first loop is fetching all the destination and the second loop fetching the favorites destination.
Note:-Here I am showing only logic code not complete HTML or other PHP code
<?php foreach($listing_data as $list){ ?>
<?php foreach($favorites as $fav){ if($fav['link_id']==$list['id']){?>
<li class="pull-right"> <a class="Theme" id="liked"><i class="fas fa-heart"></i> </a> </li>
<?php } else {?>
<li class="pull-right"> <i class="far fa-heart"></i> </li>
<?php } } }?>
Just add a helper variable
and take out the html in 2th foreach.
$like = false; in each Site
Then in each site you loop $favorites, then walk in $favorites for check if TheSite is liked;
after second foreach you should compare if $like is true for use class "fas" or false for use class "far"
<?php foreach($listing_data as $list){
$like = false;
foreach($favorites as $fav){
if($fav['link_id']==$list['id']){
$like = true;
}
}
if($like){ ?>
<li class="pull-right">
<a class="Theme" id="liked"><i class="fas fa-heart"></i></a>
</li>
<?php } else { ?>
<li class="pull-right">
<i class="far fa-heart"></i>
</li>
<?php
}
}
?>
This is just a refactoring of the code to make it look a bit cleaner.
The links are not included as they are ? and also use id's that will not be unique.
So the code could become something like...
<?php foreach ($listing_data as $list): ?>
<?php
foreach ($favorites as $fav) {
$like = ($fav['link_id'] == $list['id']);
}
?>
<li class="pull-right">
<?php if ($like): ?>
<span>More Sensible Link 1</span>
<?php else: ?>
<span>More Sensible Link 2</span>
<?php endif; ?>
</li>
<?php endforeach; ?>
So hey there as the title said I am looking for away to make my categories with subcategories. I been looking in stackoverflow for what I need but none has help me of the examples..
Here is how my table look like
So I know what I want and what I need but I have no idea how I can do that possible
I have to SELECT * FROM categories ORDER by position ASC
I have to check if parent_id is bigger then 0.
I have to remove the parent_id from my navbar and show them only under the category name where it should be by dropdown menu .
But I have no idea how I could do all of that ..
Here is how I am selecting only my categories and display them
$catsq = mysqli_query($con,"SELECT * FROM categories ORDER by position ASC");
while($catinfo=mysqli_fetch_assoc($catsq)) {
echo '
<li class="nav-item'.(isset($_GET["cat"]) && $_GET["cat"]==$catinfo["id"] ? " active" : "").'">
<a class="nav-link" href="./index.php?cat='.$catinfo["id"].'">'.$catinfo["name"].'</a>
</li>
';
}
and it's look like this
<ul class="nav navbar-nav">
<li class="nav-item">
<a class="nav-link" href="cat=1">TestCat</a>
</li>
<li class="nav-item">
<a class="nav-link" href="cat=2">TestCat2</a>
</li>
<li class="nav-item">
<a class="nav-link" href="cat=3">TestSub</a>
</li>
</ul>
but I want It to look like this
<ul class="nav navbar-nav">
<li class="">TestCat</li>
<li class="dropdown ">
//TestCat2 have to doing nothing always.
TestCat2</i>
<ul class="dropdown-menu">
<li><a class="nav-link" href="cat=3">TestSub</a></li>
</ul>
</li>
</ul>
when the parent_id is more then 0..
If anyone can help me with this would be great..
Thanks to everybody.
There are several approaches you can take:
Build an array
Nested queries
Recursion
Array
This approach builds a data structure that you can iterate through in your view. Working example
<?php
// get db connection...
// create categories array
$stmt = mysqli_query($con, "SELECT * FROM categories ORDER BY position ASC");
while( $row = mysqli_fetch_assoc($stmt)) {
// $category[ $row['parent_id] ][ $row['id'] ] = $row; // use if you need to access other fields in addition to name
$category[ $row['parent_id] ][ $row['id'] ] = $row['name'];
}
// other php stuff...
?>
<html>
... snip ...
<ul class="nav navbar-nav">
<?php foreach($category[0] as $id => $name): ?>
<?php if( isset( $category[$id]) ): ?>
<li class="dropdown ">
<?= $name ?>
<ul class="dropdown-menu">
<?php foreach($category[$id] as $sub_id => $sub_name): ?>
<li><a class="nav-link" href="?cat=<?= $sub_id ?>" ><?= $sub_name ?></a></li>
<?php endforeach; ?>
</ul>
</li>
<?php else: ?>
<li class="">
<?= $name ?>
</li>
<?php endif; ?>
<?php endforeach; ?>
</ul>
Nested Queries
This method is easiest to display using an imaginary class that does all the sql stuff behind the scenes. For the sake of argument, we will assume a class Category that has a method named listByParent($parent_id) which returns a list of rows having the designated parent_id.
<?php
$cat = new Category();
$topLevel = $cat->listByParent(0);
?>
<html>
... snip ...
<ul class="nav navbar-nav">
<?php foreach( $topLevel as $topRow ): ?>
<!-- note, this method is run on every iteration of top level categories -->
<?php $subRows = $cat->listByParent($topRow['id']) ?>
<?php if( count($subRows)): ?>
<li class="dropdown ">
<?= $topRow['name'] ?>
<ul class="dropdown-menu">
<?php foreach($subRows as $row): ?>
<li><a class="nav-link" href="?cat=<?= $row['id'] ?>" ><?= $row['name'] ?></a></li>
<?php endforeach; ?>
</ul>
</li>
<?php else: ?>
<li class="">
<?= $topRow['name'] ?>
</li>
<?php endif; ?>
<?php endforeach; ?>
</ul>
Recursion
Using recursion would allow you to have “unlimited” levels of subcategories. However, it’s a level of complexity that does not seem warranted in this case. But should you want to pursue it, note that the best way to approach it would be to make a template for the html that could be accessed programatically, with $cat->findByParent() being a key player...
i'm trying to store html tag that includes php script.
This is for the navigation menu, i'm trying to display only the menu for a particular user role.
I'm storing it this way
public function edit_module(){
$id = $this->input->post('Module_ID', TRUE);
$update = $this->db->update('ref_modules', array('Module_Name'=>$this->input->post('Module_Name', TRUE),
'Module_Menu'=> htmlspecialchars($this->input->post('Module_Menu')),
'UpdatedBy'=>$this->session->userdata('user_id')), "Module_ID = '$id'");
if($update){
return TRUE;
}
}
For display
<!--Menu-->
<!--================================-->
<div id="mainnav-menu-wrap">
<div class="nano">
<div class="nano-content">
<ul id="mainnav-menu" class="list-group">
<!--Category name-->
<li class="list-header">Navigation</li>
<?php if($this->data['menu']): ?>
<?php foreach($this->data['menu'] as $row): ?>
<?php echo htmlspecialchars_decode($row->Module_Menu); ?>
<?php endforeach; ?>
<?php endif; ?>
</ul>
</div>
</div> <!-- nano -->
</div><!-- mainnav-menu-wrap -->
<!--================================-->
<!--End menu-->
When i view the source, its fine but when i click the link, special characters are showing.
http://localhost/folderName/%3C?php%20echo%20base_url(%27citizens%27);%20?%3E
Here's a sample value that i am inserting
<li class="<?php echo ($title == 'Citizens' ? 'active-link' : '');?>">
<a href="<?php echo base_url('citizens'); ?>">
<i class="fa fa-user"></i>
<span class="menu-title">
<strong>Citizens</strong>
</span>
</a>
</li>
Any idea guys? Thanks in advance!
Inserting Html into database For Different user role is not the right way. You can use if Conditions To show your Menu for different User roles.
I'm trying to make an active navigation bar using PHP where the current page will be highlighted or colored in the navigation bar. The code I used:
<ul class="topmenu">
<li <?php if($_GET['page']="home") { ?> class="active" <?php } ?>>
<b>Bienvenue</b>
</li>
<li <?php if($_GET['page']="livres") { ?> class="active" <?php } ?>>
<b>Livres</b>
</li>
<li <?php if($_GET['page']="bibliotheque") { ?> class="active" <?php } ?>>
<b>Bibliothèque</b>
</li>
<li <?php if($_GET['page']="universite") { ?> class="active" <?php } ?>>
<b>L'université</b>
</li>
<li <?php if($_GET['page']="contact") { ?> class="active" <?php } ?>>
<b>Contact</b>
</li>
</ul>
The code will put the attribut in the class active if the page is the current page in the navigation bar. However, all the attributs will be given the class active in this case. How do I fix this?
P.S: I am not looking for any JS or jQuery alternatives, I'm trying to make this work with PHP only.
You could use $_SERVER['SCRIPT_NAME'].
<ul class="topmenu">
<li <?php if($_SERVER['SCRIPT_NAME']=="/home.php") { ?> class="active" <?php } ?>><b>Bienvenue</b></li>
<li <?php if($_SERVER['SCRIPT_NAME']=="/livres.php") { ?> class="active" <?php } ?>><b>Livres</b></li>
<li <?php if($_SERVER['SCRIPT_NAME']=="/bibliotheque.php") { ?> class="active" <?php } ?>><b>Bibliothèque</b></li>
<li <?php if($_SERVER['SCRIPT_NAME']=="/universite.php") { ?> class="active" <?php } ?>><b>L'université</b></li>
<li <?php if($_SERVER['SCRIPT_NAME']=="/contact.php") { ?> class="active" <?php } ?>><b>Contact</b></li>
</ul>
I don't use PHP, but give the current page the active tag, and change it per file. Then a single class definition in the CSS handles changing the color for each page.
HTML:
<nav>
<a class="active" href="/home/">Home</a>
Calendar
Community
</nav>
CSS:
.active {
background-color: #4CAF50;
}
Declare page variables at the very top of each individual page.
Example: <? $page="home";?>
For each list item in your nav bar add if statment with corresponding variable and active class.
Example: <li class="<?if($page=="home"){?>active<?}?>"><b>Bienvenue</b></li>
What this does is assign each page a variable. The variable is compared in the if statements in the nav bar to determine which li gets the active class.
I'm using bootstrap 4 class. I've achieved Active Class selection something like this.
<li class="nav-item">
<a
<?php if ($_SERVER['SCRIPT_NAME'] == "/somepath/yourfile1.php") { ?>
class="nav-link active"
<?php } else { ?>
class="nav-link"
<?php } ?>
href="yourfile1.php">Home
</a>
</li>
<li class="nav-item">
<a
<?php if ($_SERVER['SCRIPT_NAME'] == "/somepath/yourfile2.php") { ?>
class="nav-link active"
<?php } else { ?>
class="nav-link"
<?php } ?>
href="yourfile2.php">Home
</a>
</li>
Repeat this logic for further li tags. Hope this helps someone else.
The code work correctly if you use "==" instead of "=" in The if construct
Еxample:
if($_GET['page'] **==** "home")...
Instead:
if($_GET['page'] **=** "home")...
Hope this helps someone else...
My code doesnt work properly and it does now shows any error or any clue, what am I missing here ? any hints ? TIA
<?php if(isset($_SESSION['user_session_organizer']))
{ ?>
<li>VIEW TRIPS</li>
<?php } ?>
<?php
elseif(isset($_SESSION['user_session']))
{
?>
<li>VIEW TRIPS</li>
<?php }else{ ?>
<li><a data-toggle="modal" href="#organizer" class="smoothScroll">ORGANIZE TRIPS</a></li>
<?php } ?>
One unnecessary <?php and else if is in wrong way, do like below:-
<?php if(isset($_SESSION['user_session_organizer'])){ ?>
<li>VIEW TRIPS</li>
<?php } elseif(isset($_SESSION['user_session'])){?>
<li>VIEW TRIPS</li>
<?php }else{ ?>
<li><a data-toggle="modal" href="#organizer" class="smoothScroll">ORGANIZE TRIPS</a></li>
<?php } ?>
Note:-
Always add
error_reporting(E_ALL);ini_set('display_errors',1);
on top of your each php page to prevent yourself from a situation like:-"White Screen Of Death"
(It will on the error reporting setting for all type of errors and every error will displayed on the page if any occur).
Thanks
Try this, your else if is wrong ?> is a close tag and then the compiler dont understand the elseif, better this:
<?php if(isset($_SESSION['user_session_organizer']))
{ ?>
<li>VIEW TRIPS</li>
<?php }elseif(isset($_SESSION['user_session']))
{
?>
<li>VIEW TRIPS</li>
<?php }else{ ?>
<li><a data-toggle="modal" href="#organizer" class="smoothScroll">ORGANIZE TRIPS</a></li>
<?php } ?>
This is easier to read and to debug:
<?php if (isset($_SESSION['user_session_organizer'])) : ?>
<li>
VIEW TRIPS
</li>
<?php elseif (isset($_SESSION['user_session'])) : ?>
<li>
VIEW TRIPS
</li>
<?php else : ?>
<li>
<a data-toggle="modal" href="#organizer" class="smoothScroll">ORGANIZE TRIPS</a>
</li>
<?php endif; ?>
Check about control structures.
try this, its neat and simple code.
<?php if (isset($_SESSION['user_session_organizer'])): ?>
<li>VIEW TRIPS</li>
<?php elseif (isset($_SESSION['user_session'])): ?>
<li>VIEW TRIPS</li>
<?php else: ?>
<li><a data-toggle="modal" href="#organizer" class="smoothScroll">ORGANIZE TRIPS</a></li>
<?php endif; ?>
