I'm looking to add a simple IF statement to check whether a custom field is selected, and if so, add the code 'display:none'.
I have the code I want to add:
if( get_field('my_custom_field') )
{
echo "";
}
else
{
echo "style='display:none'";
}
But, if I add this code where I want it, it throws an error, plus, becaus eof where it's being placed, no matter what other php type code I add, it throws up an error, I believe it's because it's in some kind of loop it's not allowing it, hopefully you'll be able to assist, here is the code it's sitting within:
$offices.= '
<div class="office_section" id="office_part_'.$locator.'">
<h1>'.$officetitle.'</h1>
'.$room_specs.'
<div class="office_dimensions_holder" *** this is where I would like to
add custom IF statement, but doesn't allow me to ***>
<div class="dimensions">
<div class="dimension_sml">Dimensions: </div>
'.$dimension1.'
I imagine it's because it's within the $offices.= ' call, so would appreciate the correct syntax to allow me to check the custom field I have recently added is true and if not...then add a display:none.
Looks like this question about php syntax...
Correct one should looks like:
$offices.= '
<div class="office_section" id="office_part_'.$locator.'">
<h1>'.$officetitle.'</h1>
'.$room_specs.'
<div class="office_dimensions_holder" '.(get_field('my_custom_field') ? "" : "style='display:none'").'>
<div class="dimensions">
<div class="dimension_sml">Dimensions: </div>
'.$dimension1.'
I ended up entering this outside my code and then called the conditional inside it:
$showdimensions = get_field('show_dimensions');
if(!empty($showdimensions)){
$showdimensions = 'style="display:none"';
} else {
$showdimensions = '';
}
Then within the original code added:
'.$showdimensions.'
to pull in the display:none if the checkbox was not checked.

I have WHMCS setup, and i am trying to make a message bubble that would show when someone access it with the specific link.
Like when someone access this link, they will see normal page - https://example.com/billing/clientarea.php?action=details
But if someone access https://example.com/billing/clientarea.php?action=details&status=incomplete
They will get a message.
I have already setup the message, and it is showing on the default link. But i do not know how to set it up on the 2nd link only? I am using WHMCS.
Can anyone guide me?
Code for message bubble.
<div class="alert alert-danger">
<strong>The following errors occurred:</strong>
<ul>
<li>Please enter your address and click on save to proceed. Once Saved, then only you will be able to access the client area.</li>
</ul>
</div>
EDIT: Solution Added
thanks a ton for your help #symlink, your method works on PHP, but for WHMCS/smarty php, it needs other code, a very simple code that too, lol.
{if $smarty.get.status eq incomplete}
{include file="$template/includes/alert.tpl" type="info" msg="Please fill the form to continue with our services."}
{else}
{/if}
If the $GET param exists, add a class to the message div that makes it appear:
PHP/HTML
<?php
$class = "";
if(isset($GET["status"]) && $GET["status"] === "incomplete"){
$class = "show";
}
?>
<div class="alert alert-danger <?php echo $class ?>">
<strong>The following errors occurred:</strong>
<ul>
<li>Please enter your address and click on save to proceed. Once Saved,
then only you will be able to access the client area.</li>
</ul>
</div>
CSS
.alert.alert-danger{
display: none;
}
.alert.alert-danger.show{
display: block;
}
If you edit templates, it makes it harder to keep your WHMCS up to date. I would recommend using a hook to output some JS to inject the appropriate alert to your page.
Perhaps the ClientAreaFooterOutput hook point? https://developers.whmcs.com/hooks-reference/output/#clientareafooteroutput
Something like:
<?php
add_hook('ClientAreaFooterOutput', 1, function($vars) {
$status = App::getFromRequest('status'); //This is handy and sanitised
return <<<HTML
jQuery(document).on('ready', function() {
if ('{$status}' == 'incomplete') {
//Add your code here to output the alert where you wish
}
});
HTML;
});
I've made one menu work here, the other is doesn't work. I want to make both menu accessible either the "persegi" or the "persegi panjang"
<div id="content">
<div id="kirikolom">
<?php
if(isset($_GET['menu']))
{
if($_GET['menu']="persegi")
{
input_persegi();
} elseif($_GET['menu']="persegi_panjang")
{
input_persegi_panjang();
}
}
?>
</div>
You need to use "==" to equal variable, if just use "=" you give a variable value, so your code must be :
<?php
if($_GET['menu']=="persegi"){
input_persegi();
}
else if($_GET['menu']=="persegi_panjang"){
input_persegi_panjang();
}
?>
try to print and check the result of print_r($_GET['menu']);
Maybe different output when you access another url so it's not match in you if else statment.
Have been reading through multiple similar questions and went over my syntax many times, but I can't figure out why my PHP code is executing both conditions.
I'm trying to replace the url of an element with the string from a custom field if the field is not empty. If the field is empty, I want to output the permalink normally. What happens is that the code concatenates both the string from the custom field and the permalink when the field is not empty. If i remove the string in the field, it works fine.
<div class="profile-content">
<a href="
<?php
if ( the_field('direct_resource_link') != '') {
the_field('direct_resource_link');
} else {
the_permalink($id);
} ?>
"><h5><?php the_title(); ?></h5></a>
<div class="profile-footer">
Thanks!
Dan.
EDIT after comment from original poster
My initial assessment (left below for reference) was correct. You are using function that will print/echo content instead of returning it. Your if will always evaluate to false, because you are calling function that returns nothing; and PHP thinks that nothing and empty string are the same thing.
You didn't see that when field was empty, because the_field() for empty field printed empty string (or nothing at all), i.e. it didn't modify value printed by the_permalink() in any way/
According to ACF documentation, the_field() is accompanied by get_field() which returns value instead of printing it.
Your code should look like that:
<div class="profile-content">
<a href="
<?php
if ( get_field('direct_resource_link') ) {
the_field('direct_resource_link');
} else {
the_permalink($id);
} ?>
"><h5><?php the_title(); ?></h5></a>
<div class="profile-footer">
My initial post
What happens is that you run function the_field('direct_resource_link') and compare it's return value to ''; if that value is empty, you run the_permalink($id);.
It's hard to tell what the_field() is and what it is supposed to do, but I guess that it prints value instead of returning it. So if field is empty, it prints nothing, resulting in pure run of the_permalink(). If field is not empty, it prints it content and returns nothing. Since nothing is equal to empty string, PHP proceeds with else branch and invokes the_permalink() that prints additional info.
Solution: modify the_field() to return value instead of printing it, or make additional function that will query for value and return it, and use that function in if statement.
Miroslaw Zalewski already answered your question here, so this is simply to show you the kind of code needed to fix your issue:
function get_the_field($field) {
ob_start();
the_field($field);
return ob_get_clean();
}
This code will start an output buffer (which will capture all echo'd data), run the_field and return (and delete) the output buffer (the echo'd data from the_field). This means you can simply do the following:
...
<?php
$theField = get_the_field('direct_resource_link');
if ( $theField != '') {
echo $theField;
} else {
the_permalink($id);
}
?>
...
This can all be simplified. the_field() echoes a meta value. You don't want that...Instead, you want to return the value to check it, before conditionally echoing it. You can do this using get_field().
In the simplest form, your final code would look like the following:
<a href="<?php get_field('direct_resource_link') ? the_field('direct_resource_link') : the_permalink($id); ?>">
<h5><?php the_title(); ?></h5>
</a>
I have an active session in my page using: $_session_start(); I want to hide part of my form and show another based on the users previous entries.
Basically I offer Direct Deposit and Paper Check I want to be able to have the user only see the fields required for them to complete previously (in signup so the values are already in the database)
Right now the database table is set up like this:
paper_check with a value of 1 (yes pay this way) or 0 (no pay this way)
and the same thing with direct deposit. I need a way to show/hide the fields associated with each based on the users previous selections.
I typed this up but it doesn't seem to do anything. Please help me!!!!! (The class names hide and show are in my css and working properly!)
<?php
if ($_SESSION['direct_deposit'] == 1)
{
$doc->getElementById('check_payable_to')->className+" hide";
}
else
{
$doc->getElementById('name_on_account')->className+" hide";
$doc->getElementById('check_payable_to')->className+" show";
}
?>
I don't see a className property in the PHP DOM library. It looks like this is the way to add a class to an element:
$doc->getElementById('check_payable_to')->setAttribute('class',
$doc->getElementById('check_payable_to')->getAttribute('class') . " hide");
Do you have error reporting enabled? It should be warning about the unknown property.
If you want to do this in Javascript instead of PHP, have your PHP do something like:
<script>
var direct_deposit = <?php echo $_SESSION['direct_deposit']; ?>;
if (direct_deposit == 1) {
/* Do what you want */
} else {
/* Do what else you want */
}
</script>
In your question you said "I have an active session in my page using: $_session_start();" You shouldn't use $_session_start(). It should be session_start() .
className+" hide" should be className .= " hide"
By wrapping each section in it's own div like so:
<div id="paperCheck class="show">
<!--Your Paper Check Information here-->
</div>
<div id="directDeposit" class="show">
<!--Your Direct Deposit Information here-->
</div>
And then by using javascript you are able to do the following:
var direct_deposit = <?php echo $_SESSION['direct_deposit']; ?>;
if (direct_deposit == 1)
{
document.getElementById('paperCheck').className ="hide";
}
else
{
document.getElementById('directDeposit').className ="hide";
}
How can I show or hide div depending on result come from server, in the file that handle the request, I get a customer object from db, depending on user request, if I didn't find the corresponding customer I want to hide a div .
here's my php code
$customer=getCustomerViaCellPhone($link,$cellPhoneNo);
if(!$customer){
$error = 'No result found';
}
here's the view
<div id="customerInfo" class="<?php (is_null($customer))?'hide':''?>">
....
</div>
but it shows the div in both cases
You are missing the command echo in your example so it should be:
<div id="customerInfo" class="<?php echo (is_null($customer))?'hide':''?>">
....
</div>
obviously your css would also need to define a class called .hide that had display:hidden; in it.
According to your comment, $customer is not NULL, it's an object with NULL values in it. Which will return false for your is_null($customer) check because it's not NULLDocs - it is an object.
You can solve this by decoupling the output logic from your data a bit:
$customer=getCustomerViaCellPhone($link,$cellPhoneNo);
$hideCustomerInfo = false;
if(!$customer) {
$error = 'No result found';
$hideCustomerInfo = true;
}
and in the view then:
<div id="customerInfo" class="<?php echo $hideCustomerInfo ? 'hide' : ''; ?>">
....
</div>
In case this does not work, you can validate the $hideCustomerInfo flag already in you controller to see if it contains the value you expect. Additionally this simplifies your view.
Next to that ensure your CSS is correct as well to hide HTML elements with such a class.
<div id="customerInfo" style="display:<?php echo (is_null($customer))?'none':'block'?>">
Take a look at css' display and visibility options
