I've two fields with the same name name="s[]", but this creates an array, I don't need an array instead I'd like to construct a string.
I'm using these fields to submit search query to wordpress, if I will use an array I will have to mess with wordpress core, which I don't want. So my only option is to create 1 single string from two fields and submit it to query.
What do you think?
I think there are two options:
Submit the form to a different page, which redirects to the normal WordPress search page
Catch the onSubmit event using JavaScript and rewrite / add to the form data
I would prefer option 1 because it will work for browsers that don't use JavaScript. If you go with option 2, then you should not even show your two-field search interface to browsers that don't have JavaScript.

I am creating a website and it contains query form which includes timezone dropdown .
How can we add time zone drop down using Contact form 7 ??
Attached is output I want.
Thanks in advance!!
You can use the wp_timezone_choice function available within WordPress. This function returns values in <option> form so you can use something of below sort:
<select>
<?php echo wp_timezone_choice( '' ); ?>
</select>
Please note that I have passed empty string so that user can select an option. If you want any timezone to be preselected then you can pass the same timezone instead of empty string.
First of all you will need a timezone database. There are several which you can google for or donwload one from here.
Next import your data into WordPress, if you have a CSV file you can use the plugin Really Simple CSV Importer to import the timezones as a taxonomy for example.
The other option is to import the data as a separate table in your DB, it all depends on how you want to manage the data. If you want to be able to differentiate timezones between different continents/countries/regions then best to store them as a taxonomy and create parent terms for each region you want to differentiate.
Next to display them in your form, use the dynamic dropdown field available with the Smart grid-layout extension plugin.
The dynamic dropdown allows you build a select field using either a list of terms from an existing dropdown (see this video tutorial on how to use it) or using a custom filter and programmatically building the list (see this tutorial) using your database custom table if that's the way you imported your timezone data.
Last but not least, the dynamic dropdown also allows you to transform your select field into a select2 field which is handy for large lists as it allows your users to search for a particular timezone.
The app I am working on has hidden input variables set on initial load of the page. The variables need to be accessed across all pages. The reason for not converting these to session variables is the user can open another browser with different parameters and passing those value as hidden inputs make it work without any issue. What is the best possible alternative so as to get rid of these hidden inputs..I tried converting all variables into a Structure, but again the structure needs to be posted as part of form submission to make it available to subsequent pages.Another disadvantage of this app is use of frames.I don't have any code to post.
It sounds as if you want different browsers instances which are associated with the same web session to maintain their own distinct sets of data. Doing this by passing form or url variables around seems like a bad idea.
One approach that you could use would be, onSessionStart (or as required), create a structure in the users session to hold instances of the data. For example
session.data = {
someRandomKey: {
valueA: 42,
valueB: "Porridge"
}
}
Then just pass someRandomKey as a hidden form field or querystring parameter. Now, when they submit the form to update variables you use the id from the hidden form field to find the appropriate structure from session.data.
When the user needs a new instance of this form, give them some way, like a link or button, that creates a new unique key, inserts a struct in session.data with this key and populates it with whatever defaults are needed then loads the form passing along the new id as a hidden form field or querystring param again.
I am trying to get either a dropdown or selection box(prefer the later, because of the possibility to choose multiple values at once) in a webform.
In this case i already got the dropdown working, based on measures.measurement_type. The second needs to be measures.measurement, filtered by the type selected in the first dropdown.
I can not seem to get this working. I tried googling, but without succes. Can anyone help me get on the right track?
I found solutions using Arrays, but no working solution using 1 database table.
using ruby 4.2
Thanks
There are two options for this.
Using AJAX calls. Like #Ronan said in his answer, you need to make an AJAX call on the selection of first drop down (on change method). In the rails action method, you can render a JS partial where you can set the filtered items for second drop down.
Another one is totally client side. Like render all the possible items of both drop downs to client side. Meaning both type and measurements as javascript array. Then when changing the type drop down, filter the measurements array using jQuery and populate in the second drop down.
You gotta use some ajax for doing that, can't see other way. When your measures.measurement_type changes, you send a request passing that measurement_type as param for your action. In that action, you retrieve the collection of measurements based on the measurement_type passed in the param, and then return that data to be handled on your success ajax callback. On that method, with some jquery you should populate the second input with the options returned.
This is some simpler explanation... you should take some look at a more complete article for understanding step-by-step. Would suggest this one, for example: https://remysharp.com/2007/01/20/auto-populating-select-boxes-using-jquery-ajax. Good luck!
I have created Wordpress custom fields through functions.php. My code works fine, and I've few input fields and some checkboxes.
Problem is when I save post, even if I don't put content inside my form, these rows are created in DB. I'd like to do some kind of php check and avoid creation of row in DB if field content is not saved.
I tried several ways, but in most cases it would result in incorrect behaviors of checkboxes for example.
Full code is here: http://pastebin.com/embed_js.php?i=Vvnseiep
I'd appreciate your help in this matter. I'm not very experienced.
Thanks!
Here Validation part comes into play. Why cant you use Javascript to validate your input in the client environment itself and then allowing it to hit the db.
Name all of the checkboxes the same(name="meta_box_check[]"). They must still have different ID's. When the form is posted you will be given an array of values that were checked in $_POST['meta_box_check']. You can then check if the array is empty. You can also save the checkbox data as JSON data. This isn't always good practice, but will only use one data row to save any and all checkbox values.
<?php
if(!empty($_POST['meta_box_check']))
{
//process your data and save it
update_post_meta($post_id, 'meta_features_checklist', json_encode($_POST['meta_box_check']));
}
?>
This is a basic example and make sure you do some data validating before saving.
So how can I pass a value from one form to another? For example: The user select's an organization from a list and this opens up a trip form that allows a user to enter various information regarding the trip. At one place I would like to add another little pop up form where they can enter contact information (just a name and phone for POC) of the organization they are visiting.
So when that initial form opened from the selection screen it has two IDs that are simply hidden in text boxes (one being the tripID, and the other being the OrgID), so how do I pass these to the second little pop up form so that the contact information has the relative IDs with it.
Thanks.
The best approach in these cases is not to attempted to pass a bunch of variables. It is too much code, and is inflexible. For example, if you need to pass two values, what happens over the years when that requirement grows to 5 values? Trying to maintain and pass a whole whack of values is too much coding work.
Keep in mind that each form in ms-access is really a class object that you can manipulate in code. So, use a object approach here and you find you not only write less code, but your code will be more clean, more modular, no need for global vars, and code you write can often be re-used between different forms.
Here is how:
In general when one form launches another form in the 2nd form in the forms on-open event (in fact, you can even use as late as the on-load event) you can pick up a reference to the PREVIOUS form object. In other words, you can use a object approach here.
At the forms module level, for form I declare a form object as:
Option Compare Database
Option Explicit
dim frmPrevious as form
Then, in the forms on-load event, we go:
Set frmPrevious = Screen.ActiveForm
Now, any code in our form can FREELY use code, events, even varibles declared as public from that previous form in code.
So, if you want to force a disk write of the previous form, and re-load of data.
frmPrevious.Refresh
If you want to set the ID value, then go:
frmPrevious!ID = some value
And, note that you can even declare form previous as a PUBLIC variable for that form, and thus if you two forms deep, you could go:
frmPrevious.frmPrevious!ID = some value
So, simply declare a forms object in EACH forms code module (or at lest the ones where you need to use values in code). The above means any code has a ready made reference to the previous form object. Functions declared as public in a form will become a METHOD of the form, and can be run like:
frmPrevious.MyCustomRefresh
or even things like some option to force the previous form to generate and setup a invoice number:
frmPrevous.SetInvoice
or
frmPrevious.SetProjectStatusOn
So not only can you shuffle values and data back and forth, but you can easily execute features and functions that you build in code for the prevous form.
In fact as a coding standard, MOST of my forms have a public function called MyRefresh.
Note that the beauty of this approach is that you can thus read + use + set values from that previous form. This allows your code to not only receive values, but also set values in that previous form. So this approach is bi-directional. You can shuffle data and values back and forth between the forms. The other advantage here is you NOT restricted to just variables, but can use fields, control values (events, properties) etc.
This approach means that much of the previous form is now at your fingertips.
So don’t try to pass a whole whack of variables. Pass a reference to the form and you have a nice ready made object at your fingertips and it makes this type of coding problem a breeze.
The usual way would be to reference the textboxes in the initial form from the popup form, like this:
Forms!frmInitialForm!tripID
Forms!frmInitialForm!OrgID
However, this tightly binds the popup form to the initial form, so that it cannot be used anywhere else in the application.
A better approach is to use OpenArgs:
DoCmd.OpenForm "frmPopup", OpenArgs:=Me.tripID & ", " & me.OrgID
This places your two values into a string, which is passed to the popup form. You can then parse the two values out of the OpenArgs using the Split function.
