I have a php form on my site. The form ultimately produces an article submitted by the user.
One of the data fields in the form, is a drop down menu so the user can select which publication they represent.
Currently, the form works if I am only trying to display the name of their publication.
However... I would also like that name to be a clickable link to their respective publication.
In an attempt to achieve this, I set my form up like this:
Form: <select name="publication" id="publication">
<option value="http://www.espn.com">ESPN</option>
<option value="http://www.cnn.com">CNN</option>
<option value="http://www.abcnews.com">ABC</option>
<option value="http://www.cbsnews.com">CBS</option>
<option value="http://www.foxnews.com">FOX</option>
</select>
And the echo is set up like this:
Echo:
<?php $publication = htmlspecialchars($_POST['publication']); echo $publication; ?>
Unfortunately, the result produces the full URL instead of the Text Link I am trying to achieve.
Not sure how I am supposed to code the form or the echo to achieve the desired clickable text link.
It is taking the value option, not the innerHTML. One solution is to make the value the following:
<a href='http://example.org'>Example</a>
Note: You may need to escape characters for this to work.
The value of $_POST['publication'] is going to be the chosen <option>'s value, not the display name.
If you want to display the link along with the name, consider encoding the list of publications into a static array, then outputting that:
$publications = [
"media1" => "link",
"media2" => "link"
]
if (array_key_exists($_POST["publication"], $publications)) {
echo '' . htmlspecialchars($_POST["publication"]) . '';
}

I would like to know if it is possible to help me please.
It's a live ajax search that retrieves information in the database. This is the php code :
<?php
$key=$_GET['key'];
$array = array();
$connection=mysqli_connect("localhost","root","","visitor_signin_app");
$query = mysqli_query($connection, "SELECT * FROM visitors WHERE visitor_first_name LIKE '%{$key}%' AND visitor_visit_status = 'Signed Out'");
while($row = mysqli_fetch_assoc($query)) {
$array[] = '<span style="display:none; visibility:hidden">'.$row['visitor_id'].'</span>' . ' ' . $row['visitor_first_name'] . ' ' . $row['visitor_last_name'];
}
echo json_encode($array);
mysqli_close($connection);
?>
In the array I am trying to hide the 'visitor_id' and when I start typing the name in the input field it works perfect where it only shows the first name and last name, but once I select the name that displays in the dropdown then it inserts the
<span style="display:none; visibility:hidden">1</span>
So my main question is, would it be possible to hide the html that I dont want to display in the input field but the value needs to be added with the name that gets chosen. Any advice would be gladly appreciated. Thank you
This is the link where I received the code : https://codeforgeek.com/2014/09/ajax-search-box-php-mysql/
I would like to retrieve all the information from the registered person that gets selected in the dropdown list and add them as a new entry to the database.
Why not use the HTML inputwith type hidden ? See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/hidden
I think it's made exactly for your purpose.
Your question is a bit confusing to understand, but if I'm correct, what you want to do is have a hidden input field, but set the value of the input field based on the value of a different input field.
To do that, you should give your hidden field a display: none style, and use JavaScript to set it's value. Something like this:
document.getElementById('inputId').value = 'your data';
I'm bug-proofing a form that allows data editing for book entries in a database. Everything is working except for the drop-down box. The drop-down box automatically populates itself with every unique entry in a specific field in the database table, and that part works perfectly. However, when people click to edit a book all the fields are populated with that books information, and I wanted the drop-down box to default to the correct value for that book. My solution was to check each value as it populates the drop-down box against the actual book's value for that field and if they match, make it the "selected" value.
It is not working. The box is still populating fine, but it is not defaulting. Here is the code for the drop-down box.
<span style="margin-left:10px;">
Publication Type:
<select name="publicationType" >
<option value=""></option>
<option value="">-------------------------</option>
<?php
$lPub = '';
if(array_key_exists('publicationType',$_REQUEST)) $lPub = $_REQUEST['publicationType'];
$lPubArr = $datasetManager->getPublicationType();
foreach($lPubArr as $pubStr){
if($pubStr == $bookArr['publicationType']){
echo '<option '.($lPub==$pubStr?'selected="selected"':'').'>'.$pubStr.'</option>'."\n";
}
else{
echo '<option '.($lPub==$pubStr?'':'').'>'.$pubStr.'</option>'."\n";
}
}
?>
</select>
</span>
I can provide what all the variables are if needed. I don't see what I'm doing wrong, but maybe someone will be able to catch an obvious mistake.
Thank you,
Kai
Not sure this will help but try this:
<?php
$lPub = '';
if( array_key_exists('publicationType',$_REQUEST) )
$lPub = $_REQUEST['publicationType'];
$lPubArr = $datasetManager->getPublicationType();
foreach($lPubArr as $pubStr){
echo '<option '.($lPub==$pubStr?'selected="selected"':'').'>'.$pubStr.'</option>'."\n";
}
I removed this condition:
f($pubStr == $bookArr['publicationType'])
since I didn't get what the $bookArr['publicationType'] is used for, perhaps you left it there by mistake
I am working on an existing wordpress website.
Users has field "user-country" (actually, I do not know how this field is created in wordpress, but it works).
In the registration form, user can choose one specific country.
However, now this country list is note defined "anywhere". It is created explicitly in the code:
<option value="Afghanistan" <?php if($current_user->user_country == 'Afghanistan') echo 'selected';?>>Afghanistan</option>
<option value="Albania" <?php if($current_user->user_country == 'Albania') echo 'selected';?>>Albania</option>
<option value="Algeria" <?php if($current_user->user_country == 'Algeria') echo 'selected';?>>Algeria</option>
<option value="American Samoa" <?php if($current_user->user_country == 'American Samoa') echo 'selected';?>>American Samoa</opt
etc.
The client wants to changed this list (from country to city). So i need to add other values. I do not want to write all values in the code. I would like to create some list with these values in wp-admin.
What is the best way to create a predefined values list? And these are not custom fields for posts.
EDIT:
I want to store values in DB, so admin can modidfy these values from wp-admin.
Actually, it is not so important whether it is DB or other option like XML.
I just want this list to appear as dropdown when user is registering and also to wp-admin to modify values of this list.
Also, a question come to my mind - is it a normal practice to store user custom fields like country or city in DB? Or maybe it is ok to define them in code explicitly?
Well, if you want the administrator to be able to modify the list, then DB is likely the best option here.
I would do something like this (in WordPress):
// put a default (initial) list in the database, if there isn't one there yet
if(!get_option('my_country_list')){
// store it as a |-delimited string, because WP serializes arrays,
// and this would be too much here
$data = 'Albania|Algeria|Disneyland|etc';
update_option('my_country_list', $data);
}
Now, later where you need that list, simply get it from the db:
$countries = get_option('my_country_list');
// turn it into an array
$countries = implode('|', $countries);
// generate the select field
$html = '';
foreach($countries as $country){
$checked = '';
if($current_user->user_country == $country)
$checked = 'selected="selected"';
$html .= sprintf('<option value="%1$s" %2$s> %1$s </option>', $country, $checked);
}
printf('<select> %s </select>', $html);
I guess you'll also have some kind of administration form for the options, where the administrator can modify entries from this list. This could be a textarea. When it gets submitted you update_option() again (replace new lines with |)
I have created and html form which have a drop down list.
This drop down list is populated from database.
<select name="classes">
<?php
foreach() {
?>
<option value="<?php echo $id ?>"><?php echo $name ?></option>
<?php
}
?>
</select>
Now I want to get the $id and $name both. How will I do this?
I have tried this
echo $_POST['classes'];
But it only displays the $id of the select item. And I want $id and $name both.
You can't. One possibility would be placing both infos inside the value attribute, and then separating them back again with php (by using a delimiter):
<option value="<?php echo $id.'|'.$name; ?>"><?php echo $name ?></option>
In PHP:
$datas = explode('|',$_POST['classes']);
$id = $datas[0];
$name = $datas[1];
But that's not how the system is meant to be. Usually the $name would be used only as a "friendly" info for the user, cause the value might sometimes just be an INT and user won't understand what that int refers to, so we give him a word description in order to choose an option: but what you would only care of is that value indeed, which you can always use to get again the description that comes along with it (by a search to the database, for ex.)
As far as I know, when you submit that form, only the value is going to be carried over. If there is no value then the inner HTML becomes the value.
What I'd do is:
<select name="classes">
<?php
foreach($classes as $id => $name) //i'm guessing here, is this what you meant?
{ ?>
<option value="<?php echo $id.'|'.$name ?>"><?php echo $name ?></option>
<?php } ?>
</select>
In case you are not familiar, the period is the concatenation operator. Think of it as glue for pieces of a string. So I'm gluing $id to the left of "pipe" and then gluing $name onto the end of that.
Then in your handler, use split or explode to separate the two values on the pipe.
Actually, I'd do it a little different, echoing more and going in and out of php/html less, but I tried to leave your code intact as much as possible.
append name to Id and pass it as value,,and explode name from the other end
You want is and name both so while storing option value ,
put like this
<option value="<?php echo $id."_".$name;?>"><?php echo $name?></option>
and on posting data just explode the value you will get both is and name
Sending form means only sending 'value' for select field (treat 'name' in option as a label only). You can simply fetch 'name' from database when you have 'id' while handling form submission.
I've read other questions on here that dealt with what I am looking for. But it still did not help me.
I want to have multiple values in an option of the select tag of a form that will be posting the information onto a different file that is viewable to the visitor by iframe. Example of what I am trying to do:
The following is on the file: Form.php
<div>
<form action"blank.php" method="post" target="box">
<select name="g1">
<option name="g1" value="Value 1, Value 2"> Text </option>
<option name="g1" value="Value 1, Value 2"> Text Blah </option>
</select>
<input type="submit" />
</form>
</div>
<iframe src="blank.php" name="box"></iframe>
The Following is a long the lines of what I want to appear on the: blank.php which is visible by iframe.
Option 1 or 2 value's should appear like this
[ Value 1 ] [ Value 2 ]
An Example:
Its a drop down menu that will post two seperate values when you select one option.
Like if I selected an option that says Hola - hello and it will post:
[Hola] means [Hello].
and the option tag would have the values as:
<option name="g1" value="Hola, Hello">Hola - Hello</option>
Sounds like you want to build an array of your form fields where multiple values are allowed. Read the PHP manual for more.
From the manual:
How do I get all the results from a select multiple HTML tag?
The
select multiple tag in an HTML construct allows users to select
multiple items from a list. These items are then passed to the action
handler for the form. The problem is that they are all passed with the
same widget name. I.e.
<select name="var" multiple="yes">
Each selected option will arrive at the action handler as:
var=option1
var=option2
var=option3
Each option will overwrite the contents of the previous $var variable.
The solution is to use PHP's "array from form element" feature. The
following should be used:
<select name="var[]" multiple="yes">
This tells PHP to treat $var as an array and each assignment of a
value to var[] adds an item to the array. The first item becomes
$var[0], the next $var[1], etc. The count() function can be used to
determine how many options were selected, and the sort() function can
be used to sort the option array if necessary. Note that if you are
using JavaScript the [] on the element name might cause you problems
when you try to refer to the element by name. Use it's numerical form
element ID instead, or enclose the variable name in single quotes and
use that as the index to the elements array, for example:
variable = document.forms[0].elements['var[]'];
First of all, you don't need a name attribute on each of your <option> elements. Just the <select> box.
Second of all, I think all you need is the handy dandy explode function. You'll get the value like this...
$values = $_POST['g1'];
...and then split them into an array like this...
$values = explode(', ', $values);
...and finally just access the values like so:
$value1 = $values[0];
$value2 = $values[1];
I know that this is in the PHP section, but what you are trying to do would be much easier to achieve with javascript. If you change the iframe tags to:
<div id="valueDisplay"></div>
and add an ID and listener to the select
<select name="g1" id="dropDown" onchange="showValues()">
<option name="g1" value="1"> Text </option>
<option name="g1" value="2"> Text Blah </option>
</select>
You just write a little script like this and put it in the body somewhere:
<script type="text/javascript">
function showValues(){
var outDiv = document.getElementById('valueDisplay');
var selectValue = document.getElementById('dropDown').value;
var divText;
if(selectValue == 1) divText = '[ Value 1 ][ Value 2 ]';
if(selectValue == 2) divText = '[ Value 1 ][ Value 2 ]';
outDiv.innerHTML = divText;
}
</script>
To achieve what you are trying to do with iframes would be more difficult. It would require you to use javascript/jquery to post the data within the iframe.
Note that using onchange="" is no longer the accepted method of adding listeners. It is just easier if you are not familiar with javascript.
