I have this code snippet in PHP:
if (strcasecmp($_POST['method'], 'assignId') == 0) {
$username = $_POST['username'];
$response['code'] = 1;
$response['status'] = $api_response_code[$response['code']]['HTTP Response'];
$sql = "CALL new_person('$username')";
if (($result = $conn->query($sql)) === TRUE) {
$row = $result->fetch_assoc();
$response['data'] = $row;
}
deliver_response($response);
new_person is a stored procedure which returns an id, it has been tested and works fine and deliver_response returns JSON format of the input. It has also been tested and works fine.
Why do POST Requests return 404 error?
The stored procedure is being executed, but it doesn't return the result. Finally, when I change the POST method to GET and make a get request instead it works fine!
404 Error means that the page that has to process the post request can't be loaded or not exists. You have to check the php and server logs and maybe you can find a answer to your question.
Prefix everything, especially your variables. The names you are using are used by WordPress internally (see the comment form), so WordPress might try to do something with your form values. If that fails you get an error.
While $_GET problems are usually rather easy to debug, $_POST and $_REQUEST names are not so simple.
The following list is probably not complete. But its bare length tells us a lesson:
Avoid any name you can find in a dictionary. Prefix your form names.
List of reserved names in $_POST and $_REQUEST used by WordPress 3.5
These names might have side effects when used in themes or plugins. Some are used on specific pages only (removeheader), others on multiple pages or requests. Avoid them all if you can.

Your code starts with if (strcasecmp($_POST['method'], 'assignId') == 0) {
and the if statement is never closed, so your code runs only on post method
I assume deliver_response throw the 404
Please make sure that you have used the "POST" method in the form of the previous page.
Use the flower brackets properly(you have missed one ending flower bracket for first if condition)

I have 2 pages. One is devices and the other is cars. I also have detail_car page and detail_device page which are show the detail of each element relate to the name. I want to save and get comments for each specific devices and cars separately. For example in the detail_device page with and $id=2, when users write a comment about device whit the id of 2, I want to save this comment as meta_key=device_id and meta_value=2.
then after approving comment, it'll be enable in the detail_device with id =2 not to other devices.
function add_custom_comment_page( $comment_id, $page, $element_id ) {
$page_array = ['devices', 'cars'];
if (!empty($page) && in_array($page, $page_array)) {
add_comment_meta($comment_id, $page.'_id', $element_id);
}
}
how and where to pass $page?
You can call the comments in with get_comment in your template.
get_comment
I would like to check, if a given number has been attributed to a custom field.
How can I do that, without specifying the post ID?
details:
I created a custom post type in which I store a client number and wether or not the client has booked a service.
The service is provided by handing the client a little code snippet (iframe, source is the url to said file in their website) so they can display some information.
I know want to do the following: I attach the clientnumber to the given url, like so: www.example-url.org?nr=123
If there is no number after the url, some fail message is displaied (I already managed to do that).
Now I want to check if the client number exists at all in my database. And only then should the booked information be displaied.
I checked the get_post_meta, but I need the post ID. Can I check wether the number exists without knowing the post ID?
Try this snippet,
global $wpdb;
$metas = $wpdb->get_results(
$wpdb->prepare("SELECT meta_value FROM $wpdb->postmeta where meta_key = %s", 'add_your_key_here')
);
echo '<pre>';
print_r( $metas );
echo '</pre>';
Hope this will helps you.
For more information,
How we get_post_meta without post id
You can achieve using custom query in wordpress. For that I create one function which will help you to check if this customer number is exist or not. Please have a look at below method.
$clinetnumber=get_meta_value_using_key($meta_key); // call the method
// check if custom number is exist or not
if(!empty($clinetnumber) && $clinetnumber!=0)
{
echo "Customer number is already registered";
}
else
{
echo "Customer number is not registered";
}
function get_meta_value_using_key($meta_key)
{
global $wpdb;
$query="SELECT meta_value FROM $wpdb->postmeta WHERE meta_key = %s "; // meta query by key
$result=$wpdb->prepare($query , $meta_key);
$value = $wpdb->get_var($result); // get result of quesry
return $value; // return value
}
I have the following form on a wordpress template page. I'm getting a 404 error each time i submit the form but I'm not using any of the reserved workpress parameter names in the form.
<?php

if(isset($_POST['form-submitted']))
{
if(trim($_POST['runner']) === '') {
$runnerError = 'Please enter runner runner.';
$hasError = true;

$runner = trim($_POST['runner']);
}
if(trim($_POST['racenumber']) === '') {
$numberError = 'Please enter a race number.';
$hasError = true;
} else {
$racenumber = trim($_POST['racenumber']);
}
$race = trim($_POST['race']);
error_log($race.' '.$runner.' '.$racenumber);

foreach($races as $racez)

I've customised my 404 page to dump the $_POST values so i'm sure the parameter values are being submitted.
[racenumber] => 5
[race] => 2596
[runner] => 5
[first] =>
[last] =>
[gender] =>
[dob] =>
[standard] =>
[company] =>
[form-submitted] => true
Can anyone explain my the logic in my 'isset($_POST['form-submitted'])' is not being exercised?
The generated html
<form action="http://localhost/registration/" id="form" method="POST">
<div class="one_half">
<b>Race Details</b><br><br>
RaceNumber<input name="number" id="number" type="text"><br><br>
Race<br>
<select name="race" id="race">
<option value="2596" id="2596">4-Mile-M</option>
<option value="2595" id="2595">2-Mile-W</option>
</select>
EDIT
I've changed the code where is set the values of the select dropdown to use an incrementing int value rather than using sprintf to map a string value to an int value. When the first element is selected the form submits, if the second option is picked i get a 404!
$races = // magic array
$selectRaces = '<select name="race" id="race">';
$i=0;
foreach($races as $racez)
{
$selectRaces .= sprintf('<option value=%d>%s</option>',$i++,$race->name);
}
Problem is that WordPress have some words reserved and it will throw that error when submitting forms:
Some of the words that I found myself and surfing the web are:
Custom post type names
taxonomy names
"name"
"day"
"month"
"year"
"category"
"title"
So be careful when creating a a custom form and try to name your inputs with some prefix. In my case, I had a custom post type called "history" and I was naming the input the same way.
Have you tried resetting your permalinks?
Could be an issue there somewhere.
It doesn't seem or look like the issue is isset($_POST['form-submitted'])'
It's possible your page name is being used another plugin.
WordPress's get_permalink() is generating a URL that is being injected into your output HTML's form tag.
If you look at the HTML source, as it appears in your browser (eg right-click, view-source or right-click, inspect element), find this:
<form action='some_url_here' ...>.
I would expect that this URL should probably be the same as the one that you're currently browsing... ie it tells the browser to send the details back to that same PHP file to process its results.
Type unique Name and ID try this form
<form action="'.get_permalink().'" id="form" method="POST">
[one_half last="no"]
<b>Race Details</b><br/>
RaceNumber<input type="text" name="racenumber" id="racenumber"/><br/>
Race'.$selectRaces.'<br/>
[/one_half]
[one_half last="yes"]
<b>Runner Details</b><br/>

I had the same issue but I found when I submitted empty input fields (without any value in input field) that's working fine then I leave few input fields remain empty and place value in others which was also working fine.
That's means the issue was one of my input field not in wordpress or
in my code.

$ap_product is the associated product (simple product). Even though its a simple product, I can't use the method getResource(), because $ap_product is in catalog/product_type_configurable class. I know multiple ways to get the value of color attribute (ex: 255 stands for red) but I can't get the actual text "Red".
getResource()->getAttribute("color");
if($attribute->usesSource()){
$apColorSizeValue = $attribute->getSource()->getOptionValue($test);
}
Also this method would not work with, because its an associated product, not just a simple product.
$_product->getAttributeText('color');
I've also tried to reload a product model but loading that associated product id. That didn't work either. So right now I have the associated product id and associated product attribute color value to work with. I need to get associated product attribute color text.
This work for me
$_associatedProduct = $ap_product->getId();
$_colorAttributeId = Color_ID
$query = "select cpei.value as id,eapv.value as value from catalog_product_entity_int cpei LEFT JOIN eav_attribute_option_value eapv on cpei.value = eapv.option_id where cpei.entity_id=" . $_associatedProduct. " and cpei.attribute_id = " . $_colorAttributeId . " limit 1";
$color = $_readConnection->fetchAll($query);
Thank
<?php
$colname_subselect = "-1";
if (isset($_POST['title'])) {
$colname_subselect = $_POST['title'];
}
mysql_select_db($database_donedeal, $donedeal);
$query_subselect = sprintf("SELECT * FROM subcategories WHERE subcatename LIKE %s");
?>
I'm trying to show suggested categories from the title which is posted from previous page to categories.php page, example, In previous Page Field Name Title Contain Text :
## I Want My Motor Car To Sell##
Once submit it will go to categories.php which query i written above. Using LIKE function i able to get suggested categories when i write only one keyword like i written car in title field of previous page so in categories.php page suggested categories will show which contain car keyword.
No what i want is that when i posted complete ad post title like
## I Want My Motor Car To Sell##
how can i show the suggested categories like above title contain motor and car keyword, so it should show in categories.php categories contain car and motor keyword ? Got ME ?
I m using innodb so MATCH method will not work, any other prefer method would be much appreciated please...
$colname_subselect = "-1";
if (isset($_POST['title'])) {
$colname_subselect = $_POST['title'];
}
mysql_select_db($database_donedeal, $donedeal);
$queryString = trim(implode('or subcatename like ',explode(' ',$colname_subselect )), 'or');
$query_subselect = sprintf("SELECT * FROM subcategories WHERE " . $queryString );
Please Note that you might have to escape string for stopping sql injection.
