Output single custom meta value to metabox - php

Hopefully a very basic question.
I have a custom post type with custom meta. I had it working ok, but after some modifications I am not seeing what i expected.... PHP is a new language for me so please forgive a dumb question. I was using:
$meta = get_post_custom($post->ID); ?>
<input type="text" id="dt_location" name="dt_location" placeholder="Dog Tag" value="<?php $meta["dt_location"][0] ?>" />
in the custom metabox and it was working great however now the variable is not outputting any value. If I use var_dump I get:
string(6) "450000"
print_r also will display the value, however when I use something like:
echo "START]" . $meta["dt_location"][0] . "[END <BR>";
all I receive is
START][END
Why am I seeing data with var_dump and print_r, but not using the method that worked earlier?

The value attribute in your input is missing the echo:
<?php echo $meta["dt_location"][0]; ?>
Also, if you just need to get a value for a specific custom field, say dt_location, you can use the get_post_meta function:
<?php echo get_post_meta($post->ID, 'dt_location', true); ?>

Want to display default html if no value is present

I'm using this code to display default html if there is no value present but it's not working with a price field on a wordpress theme
<?php
$price = the_field('ct_listing_price');
if (!empty($price)) {
?>
<h4 class="price marT0 marB0" style="color:#fff;"><?php ct_listing_price(); ?></h4>
<?php
} else { echo "Price Undisclosed";}
?>
I've also tried get_field, but this won't work either. It just starts to display "Price Undisclosed" on every listing despite some having prices.
Is this field inside a form?
If so the field should have the input tag with a name <input name="price"> and the form should have a method either method = GET or method = POST.
Post is most probable in this case, if thats true than your method for checking if the variable is set would look like this:
if (!empty($_POST['price'])) {
//action here
}`

Inserting PHP into PHP existent statements

I'm using Wordpress and Custom Fields - however, I'm trying to pull a custom field with PHP to fill in the "form" code inside a PHP statement
I'm not not too familiar with PHP, but here is what I'm trying to do:
<?php $form1 = '<?php echo get_field('form_code'); ?>'; echo do_shortcode( $form1 ) ?>
I basically want to fill the form value with the value in the custom field in wordpress.
Any help would be appreciated guys <3
You do not need to do it how you typed, nor would/should it work. Just set the variable with the get field function.
<?php
$form1 = get_field('form_code');
echo do_shortcode( $form1 );
?>

Echo an input field with an echo POSTBACK value

So I'm iterating through a set value via a for loop, which will echo html input fields, every other echo'd html input field behaves as expected (including the name and id fields of the one below), however I keep getting syntax errors when trying to set the value as a postback to retain them on page submit.
Here is my code:
$type = "number".$i;
echo '<input type="text" name="'.$type.'" id="'.$type.'" value="'.<?php if (isset($_POST[$type])) { echo $_POST[$type]; } else { echo NULL;}.'" />';
Thanks in advance.
You have an extra <?php statement in the row. Since the line is echo '...'. you don't need to declare that more php code is coming. You can do something like this instead:
echo '<input type="text" name="'.$type.'" id="'.$type.'" value="';
if (isset($_POST[$type])) echo $_POST[$type];
echo '" />';
Although personally, I prefer to do something like <input [...] id="{$type}" [...]" outside of the php code, less messy.

Cannot get posted variables to echo in the form

It seems my code is correct, however the posted variables in the form will not echo in the update user settings page in the form. I have echoed the posted ids from the input in the database but I cannot get the variables to show.
I have done this in Codeigniter fine but am trying to do it in pure php with my own framework.
$users = new Users($db); comes from my init.php file that is called at the beginning of the file below.
when I
<?php var_dump($user['first_name'])?>
I get Null
<input type="text" name="first_name" value="<?php if (isset($_POST['first_name']) )
{echo htmlentities(strip_tags($_POST['first_name']));} else { echo
$user['first_name']; }?>">
Hoi Stephen,
Try print_r($_POST["first_name"]); instead of var_dump();
or just for all:
print_r($_POST);
best regards ....
add this at the top of your html page
#extract($_REQUEST);
and put is just to check and after checking remove the below line
print_r($_REQUEST);
hope this help .

How to pass array values of checkbox to next part in multi-part form

I have a site based on wordpress. I need to allow people to create posts from frontend so I have made a multi-part form which works pretty well. There are three parts of the form and each part of the form is validated before moving to the next part. Data is passed to another page through hidden inputs.
My form template looks somewhat like this ( complete code is pretty massive and irrelevant here, so just showing just the relevant parts ) which I hope is enough to give an idea how the form works.
MULTI-PART FORM WP-TEMPLATE SAMPLE CODE :
<?php
global $wpdb;
$this_page = $_SERVER['REQUEST_URI'];
$page = $_POST['page'];
if ( $page == NULL ) { ?>
<?php include_once('multiparts/form-files/first_part.php'); ?>
<?php } else if ( $page == 1 ) { ?>
<?php include_once('multiparts/validation/validate_first_part.php');
if (isset($_POST['submit-1']) && (!empty($error))) { ?>
<div class="error-head">Cannot continue registration. Error/s highlighted below.</div><br/>
<?php echo $error . '</br>'; ?>
<?php } else {
include_once('multiparts/form-files/second_part.php');
}
?>
<?php
} else if ( $page == 2 ) { ?>
//SO ON AND SO FORTH
<?php
}
?>
Recently, I have a added several checkbox fields in the form with an intention to display values of selected checkboxes, in the created posts. So here is a relevant html form code that I am currently using.
<fieldset class="work-areas">
<label for="areas" class="label">INTERESTED IN :</label></br>
<div class="work-class">
<input type="checkbox" name="workareas[]" value="administration"/>administration</br>
<input type="checkbox" name="workareas[]" value="technical"/>technical</br>
<input type="checkbox" name="workareas[]" value="creative"/>creative</br>
<input type="checkbox" name="workareas[]" value="fieldwork"/>fieldwork</br>
<input type="checkbox" name="workareas[]" value="marketing"/>marketing</br>
</div>
</fieldset>
I insert the values of these checkboxes into the post just like any other custom fields using this code: add_post_meta($pid, 'areas', $workareas, true );. In the processing part it is assigned a meta_key areas. I display it in the single.php with the code below :
<?php $areas = get_post_meta($post->ID, 'areas', true); ?>
<?php if (is_array($areas)) : ?>
<h4>INTERESTED AREAS OF WORK:</h4>
<?php if (is_array($areas)) {
foreach($areas as $area) {
echo '<li>'.$area.'</li>';
}
}
?>
<?php endif;?>
ISSUE: All this works well when the above given html form code for checkboxes is in the last/third part of the form. But it does work when the same checkbox fields is in the second part of the form. I guess it simply does not pass the array values of the selected checkboxes to the third part. Print_r shows an empty array and obviously does not display anything in the single.php too. Although I understand that the trouble is just the array of selected checkbox values, NOT being carried to the third part properly, I need help as I am noob to all this.
So the bottomline question is how do I save the array of the selected
checkboxes' values in the second part and carry it to the third part
and finally assign it to a variable which will hold the array values.
That which can be displayed in post using the code above.
THINGS TRIED : I have looked into this thread here and I am confused where I will insert my checkbox fields and not even sure it applies to my situation. I have been able to pass other text input values from one part to another part of the from using something like this :
<input type="hidden" name="eligible" value="<?php echo $eligible;?>" />
So, I tried using name="workareas[]" but did not work. I am doing print_r() for everything I am trying and till now have only been getting empty array. I am still going through tons of other threads looking for possible hints. In the meanwhile if you can help, that will be great. Thanks in advance.
UPDATE : Solved, please check the answer.
Not a WP user but your checkboxes are named "workareas" but you seem to refer to them as "areas" everywhere else.
Thanks for the suggestions in the comments but I have found a graceful and robust solution in my opinion, that is using sessions. I followed the basic idea from here which actually deals with a multipart form with sessions. Now I have the following code in my third/last part of the form, at the very beginning of the document. At this time please remember that the html checkbox fields as illustrated above in the question are in the second part.
<?php
session_start();
$_SESSION['workareas'] = $_POST['workareas'];
$result=$_POST['workareas'];
?>
The code is that is repeated during the validation of the third part is the same but this way the variable $result is still holding the values of the array of the selected checkboxes from the second part of the form.
session_start();
$result=$_SESSION['workareas'];
You can do a print_r($result) at this point and check. Furthermore, if you want to insert these array values to post in order for them to show up in the post just assign meta_key eg. areas to $result and use the code below to add it as a custom field :
add_post_meta($pid, 'areas', $result, true);
In the single.php you can use the code below to pull values from the array and show. Do not avoid if(is_array) statement else wordpress might throw an error warning: invalid arguments supplied foreach(). Goodluck.
<?php $areas = get_post_meta($post->ID, 'areas', true); ?>
<?php if (is_array($areas)) : ?>
<h4>INTERESTED AREAS OF WORK:</h4>
<?php if (is_array($areas)) {
foreach($areas as $area) {
echo '<li>'.$area.'</li>';
}
}
?>
<?php endif;?>
