I have a code like this.
<ul>
<?php foreach (getUserMainMenus($get_user_id) as $get_main_menu): ?>
<li class='has-sub'><a href='#'><span><?=$get_main_menu['menu_name']; ?></span></a>
<ul>
<?php foreach (getUserChildMenu($get_main_menu['m_id'], $get_user_id) as $sub_menu): ?>
<li class='has-sub'><a href='<?=$sub_menu['menu_url']; ?>'><span><?=$sub_menu['menu_name']; ?></span></a>
<ul>
<?php foreach (getUserSubChildMenu($sub_menu['m_id'], $get_user_id) as $sub_sub_menu): ?>
<li class='has-sub'><a href='<?=$sub_sub_menu['menu_url']; ?>'><span><?=$sub_sub_menu['menu_name']; ?></span></a></li>
<?php endforeach; ?>
</ul>
</li>
<?php endforeach; ?>
</ul>
</li>
<?php endforeach; ?>
</ul>
And the result set for the second foreach is like this.
Array ( [m_id] => 9 [menu_name] => MenuName [parent_menu_id] => 4 [menu_order] => 1 [menu_url] => menu1.php [status] => 1 )
How to check a if condition after all foreach statement.
In other words, i need to get the $sub_menu values and if there is values show the li tag.
Also - I need to check the $sub_sub_menu variable, and if there is values show the li tag.
How can i achieve that?
Thanks,
Kimz
I guess you try to create a navigation menu. Where the sub entries should only appear when the top menu item is selected by the visitor of your page.
Is that right?
Ok if so. You might have in mind that.
if a user displays your page first. you might show only the top menu items.
if then a user selects one of the top menu items he/she clicks on a link an that reloads your script with some additional information.
Now your script needs to figure out which top menu item the user selected based on the additional information.
Depending on the selection of the user you might show or hide submenu items.
What your job here is, you have to make sure that your script detects which top-menu item is clicked at.
Do you need more help, or is it clear what to do?
Ok how about this as an basic example for dynamic php menus as test.php
<?php
$menu="";
extract( $_GET, EXTR_PREFIX_ALL, "url" );
if (isset($url_menu)){
$menu=$url_menu;
echo "you selected ".$menu."<br>";
}
echo "<ul>";
// top menu 1
echo '<li>Top1';
if ($menu=="top1"){
echo "<ul>";
echo "<li>Submenu</li>";
echo "</ul>";
}
echo "</li>";
// top menu 2
echo '<li>Top2';
if ($menu=="top2"){
echo "<ul>";
echo "<li>Submenu</li>";
echo "</ul>";
}
echo "</li>";
echo "</ul>";
?>
See any top menu item hands over the additional variable "menu". This is either "top1" or "top2" in this case. Now your script on reload checks whether "menu" is already set and depending on the value of "menu" it shows the corresponding sub menu.
There is still a long way to go, because in my case I use fixed menu items where in your case you load the menu items depending on the "userid".
Let me know if the example above works at your place and if you need additional support to adopt it to your dynamically loaded menus.
Following that idea you need to replace
<li class='has-sub'><a href='#'><span><?=$get_main_menu['menu_name']; ?></span></a>
by adding for example the variable name "level0"
<li class='has-sub'><a href='<?= ?level0=$sub_menu['menu_name']; ?>'><span><? $get_main_menu['menu_name']; ?></span></a>
then you can check in you sub menu if "level0" is set as you expect it and then show or hide the sub menu items.

I am trying to set a condition for php- mysql pagination so that it can change the current page "li" to "li class="active" " to mark the current selected page. I am new to php and searching for such pagination tutorial but no luck.
I have done so far what is working but not able to mark selected page. Here $id is for detecting the current page id. How can I set if condition ( or other) so that I can mark the current page item in the pagination? Thousands thanks for helping me.
<ul class="pagination">
<?php if($id > 1) {?> <li>Previous</li><?php }?>
<?php
for($i=1;$i <= $page;$i++){
?>
<?php
if ($id>1)
{ ?>
<li class="active"><?php echo $i;?></li>
<?php }
?>
<!-- <li><?php echo $i;?></li> -->
<?php
}
?>
<?php if($id!=$page)
//3!=4
{?>
<li>Next</li>
<?php }?>
</ul>
You could change your for loop from
<?php
for($i=1;$i <= $page;$i++){
?>
<?php
if ($id>1)
{ ?>
<li class="active"><?php echo $i;?></li>
<?php }
?>
<!-- <li><?php echo $i;?></li> -->
<?php
}
?>
to:
<?php
for($i=1;$i <= $page;$i++){
$class=($i==$id)? ' class="active"' : '';
echo '<li'.$class.'>'.$i.'</li>';
}
?>
If I've understood your code properly, $page represents total pages and $id represents the current page, this will set the current page number as the active class and leave the other pages without the class
Assuming that $id is the current page number, and that $page is the total number of pages, you need to highlight only one by doing the following in your loop:
if($i==$id) // highlight
else // don’t highlight
Your main errors are that you didn’t test whether $i==$id, and you didn’t have an alternative unhighlighted version.
I really think that you should simplify your code by separating your logic from the HTML. It becomes very unreadable otherwise, and very hard to manage.
I have taken the liberty of doing just that. This way you can see where the logic does the hard work, an you only need to print the results in the HTML.
<?php
$id=3; // test value
$page=20; // test value
$li=array(); // temporary array for convenience
$template='<li%s>%s</li>';
if($id>1) $li[]=sprintf($template,'',$id-1,'Previous');
for($i=1;$i<=$page;$i++) {
if($i==$id) $li[]=sprintf($template,' class="active"',$i,$i); // Current
else $li[]=sprintf($template,'',$i,$i);
}
if($id<$page) $li[]=sprintf($template,'',$id+1,'Next');
$li=implode('',$li); // convert to string for printing
?>
<ul class="pagination">
<?php print $li; ?>
</ul>
You will also see two techniques to make things easier:
I use an array as a temporary container. It is easier to add items this way and then to implode it into a string afterwards
sprintf makes it easier to define a template string, so you can manage the HTML component more easily, and fill in the gaps when the time comes.
This is my content.php. I want to show sectors/sector_id=1.php if some one click one my side bar sectors/sector_id=1.php then sector pass an ID 1 then it shows some content then another menu then it goes to another page, but it shows only one page sector_id=0.php and when ID is 1 or 2 it shows sector_id=0.php this page:
<?php
if($id==1) include('sectors/sector_id=1.php');
if($id==2) include('sectors/sector_id=0.php');
?>
This is my side bar
<ul id="sector-nav" class="nav">
<li >
<!--Fibre-->
Fibre
</li>
<li >
<!--Hand Protection-->
Hand Protection
</li>
<li >
<!--Purification Products-->
Purification Products
</li>
<!-- others <li>'s -->
</ul>
The problem here is how you're trying to pass the variables. If you're Link is:
Fibre
This will not get through to your PHP the way you want. I would advise creating the link like so:
Fibre
When this link is followed, sectors.php will be able to get that value from $_GET['id'] variable. You can then do:
<?php
if(isset($_GET['id'])){
include('sectors/sector_id=' . $_GET['id'] . '.php');
}
?>
Now, if you do something like:
Fibre
This can be used too, but will generate a NULL value at the index called 1, $_GET['1']. So you could grab the Key versus the value if you wanted.
Hello how do you add php into an unordered list like below ?
<?php // Render the Category List
categoriesList(); ?>
<?php
into
<ul class="oi_smalldev_categories_list">
<li class="cat-item cat-item-7">
Coding
</ul>
Thank you.
This should work:
<ul>
<?php
$mycats = categoriesList();
foreach ($mycats as $cat) {
echo '<li>'. $cat. '</li>';
}
?>
</ul>
I'm guessing you want to take the results from the function and add them to your unordered list.
Basically, in your function you can create a string that is the HTML you want to output. In this case multiple tags.
You can then store it in a variable and call it with PHP further down the page.
Not the best way to handle it but I think this can do what you're after.
So, here's some pseudo code to handle that.
<?php // Render the Category List
$results = categoriesList();
?>
function categoriesList(){
return '<li>'.'category1'.'</li>'.'<li>'.'category2'.'</li>'.'<li>'.'category3'.'</li>';
}
<ul class="oi_smalldev_categories_list">
<?php echo $results; ?>
</ul>
I'm trying to put a menu together where it will sense what page is loaded. This site is not done in a CMS and is straight PHP/HTML code.
I currently have the navigation working for the primary links. There is a dropdown where I am having problems. I need to be able to see if the parent or any dropdown children are active. If one of the children are active. In the example below this is "FAQ" and the children are "FAQ1," "FAQ2," and "FAQ3."
For this example I'm using a CSS state called "active."
<style>
a{color:red;}
.active{color:blue;}
</style>
Here is the script used for the menu. The links for Home, Products, and Contact are working as expected.
<ul>
<li><a href="index.php" id="homenav" <?php if (strpos($_SERVER['PHP_SELF'], 'index.php')) echo 'class="active"';?>>Home</a></li>
<li><a href="products.php" id ="prodnav" <?php if (strpos($_SERVER['PHP_SELF'], 'products.php')) echo 'class="active"';?>>Products</a></li>
<li><a href="faq.php" id ="faqnav" <?php if (strpos($_SERVER['PHP_SELF'], 'faq.php, faq1.php, faq2.php, faq3.php')) echo 'class="active"';?>>FAQ</a>
<ul>
<li>FAQ1</li>
<li>FAQ2</li>
<li>FAQ3</li>
</ul>
</li>
<li><a href="contact.php" id ="connav" <?php if (strpos($_SERVER['PHP_SELF'], 'contact.php')) echo 'class="active"';?>>contact us</a></li>
</ul>
Can I please get some help on how I should be writing this line to let it work the way the others are?
<li>
<a href="faq.php" id ="faqnav"
<?php
if (strpos($_SERVER['PHP_SELF'], 'faq.php, faq1.php, faq2.php, faq3.php'))
echo 'class="active"';
?>
>FAQ</a>
</li>
strpos() only accepts one string per parameter, you can not give it a list.
Try this:
<?php if (in_array(basename($_SERVER['PHP_SELF']), array('faq.php', 'faq1.php', 'faq2.php', 'faq3.php'))) echo 'class="active"';?>
basename() strips the path from the filename, so you only have the pure file name
in_array() then checks if this path is in an array
array() generates an array of strings to be handed over to in_array(). Note that there are 4 separate strings, not one long one as in your code.
Use in_array for this purpose:
if (in_array($_SERVER['PHP_SELF'], array('faq.php', 'faq1.php', 'faq2.php', 'faq3.php')) echo 'class="active"';
http://php.net/manual/de/function.in-array.php
If you don't have any other pages that contain faq, you can simply use:
if (strpos($_SERVER['PHP_SELF'], 'faq') !== false)
Note that I am using !== false as strpos can return 0 when faq is found at the beginning of your string. You should probably use that for your other comparisons too.
Otherwise, go with the in_array solution of #MrTweek.
Sorry if this seems very simple I'm rather new to php.
I'm drawing data from the database using a for each loop and want to add a list item for each result to a side bar while adding a new container div to the body.
What is the best way to code this?
Any help is much appreciated.
Thanks A
Edit...
My code so far...
<?php
$iidcoversheets = $wpdb->get_results(
"
SELECT *
FROM $wpdb->trm_iid_cover_sheet
WHERE Return_ID_FK = '$trmrtnid->Return_ID_PK'
"
);
$gadcoversheets = $wpdb->get_results(
"
SELECT *
FROM $wpdb->trm_gad_cover_sheet
WHERE Return_ID_FK = '$trmrtnid->Return_ID_PK'
"
);
?>
<ul>
<?php
foreach ( $iidcoversheets as $iidcoversheet )
{
?>
<li><?php echo $iidcoversheet->business name; ?></li>
<?php
}
?>
<?php
foreach ( $gadcoversheets as $gadcoversheet )
{
?>
<li><?php echo $gadcoversheet->business name; ?></li>
<?php
}
?>
</ul>
I understand how to add the <li> items but I'm strugging on how to add a div containing some html to another div not in the <ul> tag as it seems to me this will interrupt the code for the <ul>.
Any help would be really appreciated.
Thanks A
<div>
<ol>
<?php
foreach ($uls as $ul) {
?>
<li>
<?php echo $ul; ?>
</li>
<?php
}
?>
</ol>
</div>
Ok I came to the realisation that I could simply do another exact same loop later on in the page in the div I wanted but with different output. I was trying to do it all up front save the results and output them somewhere else, unnecessary.
Clearly I was having a daft moment earlier.
Thanks for all the input.
Regards
A
