I am trying to create a template commenting system using Dreamweaver for a site. I have the form setup to submit the webpage and corresponding text to a mysql db. the webpage value is a hidden form field.
The form submits to the db okay but I want to create a repeating view for the comments. How do I reference the hidden form field so I can use it where "WHERE webpage=""" is called?
UPDATE: By repeating view I mean:
<?php do { ?>
<p><?php echo $row_InsertRecords['text']; ?></p>
<?php } while ($row_InsertRecords = mysql_fetch_assoc($InsertRecords)); ?>
My problem is I need to make partial edits to the PHP for that template so I can retrieve comments specific to the child page but Dreamweaver won't let me. It either propogates ALL of the PHP or none of it.
For a dynamic commenting system that uses the templates in Dreamweaver, you can use the following code in your dwt file:
$fname=basename($_SERVER['PHP_SELF']);
$query_ViewRecords = "SELECT * FROM commentsDB WHERE id='".$fname."'";
id can match a hidden value in your comment form defined as such:
<input type="hidden" name="IDField" value=<?php echo "\"$fname\""; ?>/>
The code above was part of code generated by Dreamweaver's DB functions that were later edited by me to add the WHERE clause. This way you can generate HTML that matched each child page when it is created by the template. Make sure codeOutsideHTMLIsLocked parameter is set to true for these changes to propagate to the child pages.

Hello I am very new to WordPress on my requirement I have created a couple of php files in wordpress theme. Where detailsform.php consists
<form method="post" name="details" action="customerdetails.php">
where after clicking submit button the form has to redirect to customerdetails.php in php it is working fine but in wordpress it is giving 404 error(page not found) I kept all new php files in the existing theme folder.
Please suggest me it is killing my time.
As wordpress has its very own specific way to handle ajax calls, wordpress has it too for post http request by form submitting. In the codex on wordpress there is more details about that.
In a brief explanation, using your functions.php file on your wordpress theme:
The first thing you need to do is set in your action attribute from your form tag, point the following url:
<form action="http://www.example.com/wp-admin/admin-post.php" method="post">
<input type="hidden" name="action" value="my_handler_function">
</form>
Once pointed, you need to add a hidden input with the name attribute action and a value attribute specifying the name of your action. Then, you need to build your handler function on your functions.php file. This is where your going to write the code you need for treat the data you will received by the global $_POST or $_REQUEST variable.
function my_handler_function() {
var_dump($_REQUEST);
die();
//request handlers should die() when they complete their task
}
Next step is to bound this function to your form by using the action hook admin_post_nopriv_ or admin_post_. The difference between these, is where your form is placed. If your form is for a custom functionality for the admin of wordpress then is private and you use admin_post hook action. If this form is part of your public content then use the admin_post_nopriv_ like in the following example:
add_action( 'admin_post_nopriv_my_handler_function', 'my_handler_function' );
As it is show in the code example above, you need to call the add_action function. In the first parameter, It is needed to pass the action hook provide by wordpress combined with the action value specify in the hidden input named action in the form, like admin_post_nopriv_$action_value. In the second parameter, you need to placed the function name you build on you functions.php file. Both are mandatory.
For matters of conventions, generally, the name of the function handler is set it as same as the value of the action input to avoid misunderstandings and gain more readability.
Onced everything is put it all together, all you have to do is test your code.
Happy coding!!
PD: If you want to clarify about this procedure of wordpress, please take a look in the wp-admin/admin-post.php file, but don't even dare to modify it.
// Put your file customerdetails.php in current theme and use following path in action:-
<form method="post" name="details" action="<?php echo get_template_directory_uri() ?>/customerdetails.php">
404 error means the action is wrong for form.
<form method="post" name="details" action="customerdetails.php">
^ ^
Correct the action to exact path of customerdetails.php
Issue must be with path (form redirection URL on submission), try with full url.
Can you share the URL at which you have put your form ??
edit your php file with template.
Ex. http://www.wpbeginner.com/wp-themes/how-to-create-a-custom-page-in-wordpress/
<?php
/*
Template Name: Customer Details Page
*/
get_header();
?>
// your php file as it is.
<?php get_footer(); ?>
now create new page with "customerdetails" name in wp admin & select "Customer Details Page" in right side column & save.
now your form action path will be as below
<form method="post" name="details" action="<?php echo get_site_url(); ?>/customerdetails">
Now your form is getting submitted & customerdetails page also receive post data.
I'm trying to do something very basic: retrieve a post value from a hidden field. The hidden field is obviously in my view file and I want to retrieve the value in my controller. I'm using the framework SimpleMVCFramework.
I have a hidden field in my projects.php file (the list with projects). When you click on a project, a method in the controller renders the clicked project and the corresponding page. This corresponding page is called project.php
The hidden field in my projects.php view:
<form method="post" action="project.php">
<input type="hidden" name="project-id" value="<?php echo $project['id'];?>">
</form>
This hidden form is displayed correctly in my lists with projects. I checked them in the console.
In my ProjectController.php, I try to retrieve the data using
$data['id'] = $_POST['project-id'];
Then, I send the $data variable with the rendered page, so that I can use the id. So every project in projects.php has a hidden file that outputs correctly. When I try and click on a project, it brings me to project.php, but when I check out the $data variable, the id is just empty.
The routing works like a charm, because e.g. $data['title'] = "Project"; works great and is visible when I check the $data variable. When I change
$data['id'] = $_POST['project-id'];
to
$data['id'] = "foobar";
the id in project.php isn't empty anymore, but shows foobar. So I guess that something goes wrong with retrieving the value.
I also tried to remove the action=".." from the form, but that also didn't work.
The thing I'm trying to achieve is so simple, that I don't understand what is going wrong. Is it possible that the problem lies with the framework and that the code is right?
Thanks in advance and sorry for my bad English.
I have a text box which extracts the content of dropdownlist.Now whenever i extract the content i too need to edit it ana save it into the database.How can i do????
Here is my code:
<?php
require'conn.php';
$select_query="Select dynamictext from tbl_content where type=1";
$select_query_run =mysql_query($select_query);
echo'Dynamictext:';
echo "<select name='dynamic text' id='names' >";
while ($select_query_array= mysql_fetch_array($select_query_run) )
{
$value=$select_query_array["dynamictext"];
echo "<option value='$value' >".htmlspecialchars($select_query_array["dynamictext"])."</option>";
}
echo "</select>";
?>
Based on the clarification I got above from #krisha above, I'm going to take a stab at answering this. You'll want to refer to my comment above, for a definition of (Option A) and (Option B), as I defined them.
Let's assume you've got (Option A) working and that (as far as the select HTML element is concerned), it is functional.
Let's also assume that you know to do the following:
Place the select tag inside of a form tag.
Set the form tag's action and method values.
Place a <input type="submit" value="Submit"> inside of the form tag.
If none of the above made sense, see here.
Once you've done everything above, that will result in the value of the HTML drop-down being available to PHP after the user clicks the Submit button and the page refreshes. How the value of the drop-down is passed through the submit process will depend on the method value you pass to the form tag. I'll assume you use method="get" (which will result in the value of the drop-down appearing in the URL after the refresh). If you want more info on get versus post, see here.
Once the refresh occurs, you use PHP's $_GET[""] to retrieve the value of the HTML drop-down. In your case, you would use $_GET["dynamic text"] (since the name of your select is dynamic text). You could set this value to a variable, like so:
$value_of_select = $_GET["dynamic text"];
At this point, you have the value the user selected from the HTML drop-down. Now, push it to the database. It looks like you already understand how to pass queries to a database. The only difference in this case is that you want to do an insert or an update, not a select.
I am having a problem where I am successfully setting a URL variable in the form of mywebsite.com/contact/?product=VAR1 from one page to another, and it will be read on the 2nd page with my simple code.
First use is fine but any thing after that is not. There is a problem with the variable not being cleared/re-read/reset. The URL Bar even reads fine in the URL bar mywebsite.com/contact/?product=VAR2 so that first part works.
But the code doesn't want to get the VAR2 part once it has stored VAR1. It just keeps re-displaying VAR1 once it is loaded once.
<?php echo htmlentities($_GET['product']); ?>
If it makes a difference, I am succesfully displaying the ?product= information inside of a jQuery value changer with this:
$(".input-text").val('<?php echo htmlentities($_GET['product']); ?>');
I have tried my own solutions like putting in a unset($product); before the last ?> but no avail.
I have a limited knowledge of PHP/jQuery and would like to use this way of setting/grabbing variable since it is simple. I am using it in jQuery because it can re-write the exact form input-box value with this variable passed along, and successfully send it in my CMS's contact form.
------------------------ updated: added code ------------------------
(I am just displaying all the code logically as I can think of)
#1: Set up the variable into the URL. The first echo getURL displays the url, I add my ?product= and then it gets the item name. This is all fine.
<a href="<?php echo Mage::getURL('webforms/index/index/id/2') ?>?product=<?php echo $_product->getName(); ?>">
#2: My form is set up within my CMS. It has a special class so I can select it exactly within my jQuery. I do not have access to all of this, it is generated by the CMS. The purpose obviously is to get selected products to be rememmberd via this Variable, and serve purpose in the contact form.
<div class="field webforms-fields-enquiryfield">
<label for="field_20">
Product in Enquiry
</label>
<div class="input-box">
<input type="text" name="field[20]" id="field[20]" class="input-text" style="" value="">
</div>
</div>
#3: Now that my area to display, & variable are set up, we use jQuery to insert the variable into the actual value of the input-text form. I am doing this because within my CMS I am not able to simply add it in. I have to use jQuery to replace the text (which is empty box anyway).
$(".webforms-fields-enquiryfield .input-text").val('<?php echo htmlentities($_GET['product']); ?>');
Hope that made more sense.
I have figured the answer to this, the problem was that the CMS Magento likes to cache certain blocks - which is why I could view it first, then my CMS would store the variable but not erase it. No matter what kind of fixes I tried to disable caching, no go.
Instead I ended up using the following code, using a # variable, and some simple JavaScript that anyone can understand. I will be using this in future projects no doubt! Very easy variable passing ...
if(window.location.hash) {
var hash_value = window.location.hash.replace('#', '');
$("my-css-input-field-or-whatever-you-want").val(hash_value);
}
The hash_value can be used in a variety of ways now I suppose, and this works well around my Magento set up, it does not get cached/stored. Grabbing the URL location & hash instead.
(And the PHP used, simplified for anyone to replace/reuse within a CMS)

We're using PHP to build a product page for a gallery website that's using GetSimple 3.0 CMS. We are trying to create a contact form that is displayed when you click a button. By default the contact form is in a DIV that's set to display: none. When you click the button it displays: block. When a user clicks the submit button for the form and calls the action it loads the contact.php file and resets the DIV to display: none resulting in the user not seeing the conformation text that their form was submitted. You can only see it by clicking on the contact button again and displaying that DIV to block manually.
We'd like the contact form DIV to persist after the submit button is clicked. I don't think showing our code would be helpful. We're just trying to find a way to implement this idea if possible.
At present our website is still early in it's development stage and it's still being hosted locally.
Thanks for any help.
use ajax submission of that particular form so that focus will not loss even the page will not be refreshed
If you can edit PHP code used for building the page, you can always display the style dynamically depending on the request, like this:
<div style="display:<?php echo (isset($_REQUEST['answer'])) ? 'block' : 'none';?>>
Thank you!
</div>
<form action="contact.php" method="post">
<input type="hidden" name="answer" />
...
</form>
You can also submit a form without reloading the page, e.g. with JQuery.Forms
If both the form and the PHP file are located in Contact.php, you could consider using this:
<div id="formWarp" <? if($_POST["contact"] == "true"){ echo 'style="display:none" '; } ?>>
<form method="POST" action="Contact.php">
<input type="text" name="something"/>
<input type="hidden" name="contact" value="true"/>
</form>
You can include any other <input>'s inside the form.
EDIT: Completely changed to reflect new information obtained to more directly address the problem.
Reading your above comments I'm fairly confident we are looking at the wrong function to edit. The wrapper element is not present in the function you posted which is what needs to have it's display toggled.
once you find that block of code we can edit it to look for the presence of post data which would indicate that the page is being loaded after a form submission has occurred (I can't promise that this won't cause it to trigger at the wrong time if there is more than one form on this page) and write in a style attribute to overwrite the default value if tested true.
Some where in that plugin there will be something defining the forms wrapper element
$html = '<div id="some-unique-id" class="some-class-name">';
You can break up this line and put a test for post data adding an inline style attribute if found
$html = '<div id="some-unique-id" class="some-class-name"'; //tag left open
if(isset($_POST) && (count($_POST))){ //Some Post Data Exists
$html .= ' style="display:block;"'; //Add display overwrite
}//Some Post Data Exists
$html .= '>'; //close the tag
The test we are performing here is if(isset($_POST) && (count($_POST))){ which is checking to make sure that A) $_POST exists and B) it has at least one element (this is using type juggling to convert a numeric result from count() into its Boolean equivalent (where anything greater than 0 will test true)
Now, as i mentioned, there may be more than one form on this page and it is possible it will be displayed afterwards which would auto show your contact form when you don't want to have it showing. Based on the example you provided in a comment it looks like this function exists within a class. If the block of code we are looking for exists within the same class it might be possible to leverage the id attribute to restrict the check to post data from the form you are interested.
$html = '<div id="some-unique-id" class="some-class-name"';
//Check for contact form specific post data
//(if $this->id is within scope and still the same)
if(isset($_POST) && (isset($_POST['p01-contact' . $this->id]))){
$html .= ' style="display:block;"'; //Add display overwrite
}//Post Data Exists
$html .= '>';
In this test we are hoping that $this exists and the attribute id of $this is the same as it was at the time that the form was originally drawn so we can look for post data that is related to the specific contact form. (the name we are looking for is based off of the code example you posted as a comment)
Unfortunately without looking at the source of the site/plugin it will be impossible for me to tell you where you can find what you are looking for. Once you find it though one of these two scenarios should hopefully take care of your problem.
Is this a publicly available plugin we could look at or something developed in-house?
