I'm using a Bootstrap multiselect plugin (https://davidstutz.github.io/bootstrap-multiselect/). The documentation says to call the plugin to the forms select id by the following:
$('#example').multiselect();
However my page is a timetable with multiple cells that are actually generated by a loop statement. Days (Mon-Sun) looped by how many units are in the database. Inside each box, is a separate form which works fine. Now i've wanted to add the multiselect plugin to add a select dropdown into the forms however I can't seem to call the plugin.
I have a $i value that increases on each loop but this will only loop the amount of times a vehicle has been added (5 vehicles, 5 loops etc.). So if I have ms_ this will work, however only for the first column as thats where it stops being unique. I have another value of $thisdate which gives me the date the current cell is on. So technically I thought I should be able to have the following:
<?php
$currentlocation = $i . $thisdate;
?>
<script type="text/javascript">
$('#ms-<?php echo ''.$currentlocation.''; ?>').multiselect();
</script>
This doesn't work. However the below does, but only for the first column.
<?php
$currentlocation = $i;
?>
<script type="text/javascript">
$('#ms-<?php echo ''.$currentlocation.''; ?>').multiselect();
</script>
Or this which works for the top column
<?php
$currentlocation = $thisdate;
?>
<script type="text/javascript">
$('#ms-<?php echo ''.$currentlocation.''; ?>').multiselect();
</script>
$i and $thisdate together would be the unique cell value.
EDIT: This was fixed by using $('.example').multiselect();
This code is working perfectly.

<?php

$date=date("Y-m-d");
?>
<div class="">
<strong>Select Language:</strong>
<select id="ms-<?php echo $i?>-<?php echo $date; ?>" multiple="multiple">
<option value="php">PHP</option>
<option value="javascript">JavaScript</option>
<option value="java">Java</option>
<option value="sql">SQL</option>
<option value="jquery">Jquery</option>
<option value=".net">.Net</option>
</select>
</div>
<script>
$(document).ready(function() {
var i = '<?php echo $i; ?>';
var current_date = '<?php echo (string) $date; ?>';
$(`#ms-${i}-${current_date}`).multiselect({
includeSelectAllOption: true,
});
});
</script>
<?php
}
?>
Give all the select elements in each cell from the same class and then call
$('.<common class name of elements>').multiselect();
Sample code:
<select class="example-getting-started" multiple="multiple">
<option value="cheese">Cheese</option>
<option value="tomatoes">Tomatoes</option>
<option value="mozarella">Mozzarella</option>
<option value="mushrooms">Mushrooms</option>
<option value="pepperoni">Pepperoni</option>
<option value="onions">Onions</option>
</select>
<br>
<select class="example-getting-started" multiple="multiple">
<option value="potatto">Potatto</option>
<option value="cucumber">Cucumber</option>
<option value="apple">Apple</option>
<option value="amazone">Amazone</option>
</select>
<script>
$(document).ready(function(){
$('.example-getting-started').multiselect();
});

I have a select dropdown with search option that displays dynamic data,its working fine,but i need to add one more feature like if the user types anything and it is not available in the option then he should be allowed to simply type and provide an input. it should not be like this that if the user's desired value is not in dropdown then he is not able to type also
The link that i am following for dropdown is this
Here is my code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.12.2/js/bootstrap-select.min.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.12.2/css/bootstrap-select.min.css" />
<select name="ddlCountry" id="Select1" class="selectpicker" data-live-search-style="begins" data-live-search="true">
<?php foreach($location as $loc): ?>
<option value="<?php echo $loc->city.', '.$loc->state;?>" ><?php echo $loc->city.', '.$loc->state;?></option>
<?php endforeach; ?>
</select>
Can anyone please give me any suggestions,
Thanks in advance.
You can use the html5 datalist feature to achieve this functionality,
<input name="ddlCountry" id="Select1" class="selectpicker" data-live-search-style="begins" data-live-search="true" >
<datalist id="Select1">
<?php foreach($location as $loc): ?>
<option value="<?php echo $loc->city.', '.$loc->state;?>" ><?php echo $loc->city.', '.$loc->state;?></option>
<?php endforeach; ?>
</datalist>
The solution requires you to capture the input as the user is typing, the other issue with the above solution, it is tricky to use select and options, instead, use input type text as in the below code.
The below code needs a bit of tweaking.
Html and PHP
<input list="select1" name="ddlCountry" class="selectpicker" data-live-search-style="begins" data-live-search="true" /><
<datalist id="select1">
<?php foreach($location as $loc): ?>
<option value="<?php echo $loc->city.', '.$loc->state;?>" ><?php echo $loc->city.', '.$loc->state;?>
<?php endforeach; ?>
</datalist>
Every time the user enters the data, we need a way to capture the new entry
AJAX and Javascript
$(document).ready(function() {
$(document).on('keyup', 'input[name="ddlCountry"]', function() {
alert($('input[name="ddlCountry"]').val());
$.ajax({
url: "{PHP url}",
method: "GET",
data: {
search: $('#Select1 option:selected').val()
},
})
.done(function(data) {
//assuming the data is returned as an array
var tmp_variable = '';
data.foreach(function(item) {
tmp_variable = tmp_variable + '<option value="' + item + '">';
})
$('#select1').html(tmp_variable);
});
});
})
I have two dropdown. I am using Jquery to load second dropdown. without jqyery My php code is working fine. but when I use with jquery second dropdown becomes empty on selection of first drop down.
First Dropdown ( Education )
$sqleducation = "select * from education order by education_id asc ";
$reseducation = mysqli_query($conn,$sqleducation);
<select name="education" id="education">
<option value="-1">Please Select</option>
<?php while($roweducation=mysqli_fetch_array($reseducation)){ ?>
<option value="<?php echo $roweducation['education_id']?>">
<?php echo $roweducation['education_name']?>
</option>
<?php }?>
</select>
Second Drop Down ( Degree)
<select name="degree" id="degree" >
<option value="-1">Please Select</option>
<?php if(isset($_POST["education_id"]) && !empty($_POST["education_id"])){
$sqldegree = "SELECT * FROM degree WHERE education_id = ".$_POST['education_id']." ";
$resdegree = mysqli_query($conn,$sqldegree);
while($rowdegree=mysqli_fetch_array($resdegree))
{ ?>
<option value="<?php echo $rowdegree['degree_id']?>">
<?php echo $rowdegree['degree_name']?>
</option>
<?php } }?>
</select>
Second dropdown is using juery to load on selection of first dropdown Education.

data:'education_id='+educationID,
success:function(html){
$('#degree').html(html);
}
});
}else{
$('#degree').html('<option value="">Select Education first</option>');

Try change below line

to

Try this.(second select tag have to place in first page in order to use $('#degree').html(...))

$sqleducation = "select * from education order by education_id asc ";

Here in ajax, you are using the
data:'education_id='+educationID,
Which is used to post the data. and the variable name will be here education_id.
And in your second page you are trying to get:
isset($_POST["education"])
this only. So on second page you have to replace education with education_id.
change:
$('#education').on('change',function(){
To:
$('select#education').change(function(){
I have a php loop that outputs a box with a form in it. At the moment if you click on the button or change one of the select boxes then the top layer is hidden and it shows another layer with a rest button on it. I want it to automatically hide the top layer if the 'todo' div has a text string longer than 3. I have tried to program this using similar programming to when the buttons are clicked/options selected. Can anybody see what is wrong with my programming? Below is the code I have used for todo.

Q: Can anybody see what is wrong with my programming?
Answer:
first thing that you should do before you debug is to fix you html document and follow the correct guidelines of calling external scripts. I also notice that you are implementing a bad habit of executing sql queries inside of your display page which is actually a common mistake that developers should avoid.
Include files such as dbcon are always located at the beginning of the code.
include 'dbconnection.php'
There is also a standard structure of html document.
example:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
</body>
</html>
Most of the time, Javascripts which is embedded internally are located at the bottom part of the html document if it is not from external js file.
Here is my html, I need to sum the value of select fields on change
<for i=0;i<3,i++) {
<select id="options_<?php echo $i ?>">
<option value="25">RS 25</option>
<option value="30">Rs 30</option>
<option value="45">Rs 45</option>
<option value="95">Rs 95</option>
</select>
}
<p id=""sum_of_select> </p>
For example if i value is 2 means i want to sum the value selected in 2 select fields (45 is selected in select 1 and 95 selected in select 2 the output should be 140 ) . How to get in jquery
PHP is server-side. JS is client side. You can't use PHP to find the sum at runtime. Here is an example of how you can do this with jQuery-
<for i=0;i<3,i++) {
<select class="sum-selector" id="options_<?php echo $i ?>">
<option value="25">RS 25</option>
<option value="30">Rs 30</option>
<option value="45">Rs 45</option>
<option value="95">Rs 95</option>
</select>
}
<p id=""sum_of_select> </p>
<script>
$('.sum-selector').change(getSum);
function getSum() {
var sum = 0;
$('.sum-selector').each(function(select) {
if(select.value) {
sum += parseInt(select.value);
}
});
alert('sum is: ' + sum);
}
</script>
first off, I recommend before asking a question on here, make sure you debug and check before submitting a question.
What your code looks like:
for i=0;i<3,i++) {
<select id="options_<?php echo $i ?>">
<option value="25">RS 25</option>
<option value="30">Rs 30</option>
<option value="45">Rs 45</option>
<option value="95">Rs 95</option>
</select>
}
<p id=""sum_of_select> </p>
Now to be honest, your code is a bit confusing. But I'll see if I can sum up something for you.
What your code should look like:
<?php
// start the loop
for i=0;i<3,i++) {
?>
<select id="options_<?php echo $i ?>">
<option value="25">RS 25</option>
<option value="30">Rs 30</option>
<option value="45">Rs 45</option>
<option value="95">Rs 95</option>
</select>
<?php
} // end the loop
?>
<!-- here will go your summary -->
<p id="sum_of_select"></p>
<script>
// and to use your PHP variable in Jquery or Javascript:
var yourVarName = <?php echo $i; ?>;
</script>
NOTE: Your file must be a PHP file to do this, else this won't work.
Hoped this helped.
I am working on a project where I am stuck at a point right now. I need to change the value of a DIV live on select of the dropdown using jQuery.
Example:
I want this:-
<select name="">
<option value="10">10 clicks</option>
<option value="20">20 clicks</option>
<option value="30">30 clicks</option>
<option value="40">40 clicks</option>
</select>
<div id="chpln">Clicks: 0 clicks</div>
When I will select option 1 the value will be displayed in place of 0 in DIV live. The problem is that as this select value fetches data from the database I am not understanding how to do it.
Example:
<select name="" id="pln" class="select-box" style="margin-top: -40px;" />
<?php while($ac_fetch = mysql_fetch_array($qur_ac)){ ?>
<option value="<?php echo $ac_fetch['adclk_clicks']; ?>"><?php echo $ac_fetch['adclk_clicks']; ?> clicks</option>
<?php } ?>
</select>
jQuery that I used currently:-
$(document).ready(function(){
$("#pln").click(function(){
$("#chpln").text("Plan: <?php echo $ac_fetch['adclk_clicks']; ?> secs");
});
});
This jquery is changing the value currently but I am getting only the first value of the database i.e., 10. When I choose different option it still displays the first value from the database i.e., 10 while it should actually display the second value that is 20. Please help me. FIDDLE will be appreciated.
click is a wrong event for selection box
you can utilize change event for your result.
$(document).ready(function(){
$("#pln").change(function(){
$("#chpln").text("Plan: "+$(this).val()+" secs");
});
});
For Dropdown, click(function() is not applicable. Use change(function().
I gave you 2 way. Use any one.
I) Method - 1 (Using Ajax)
<select name="" id="pln" class="select-box" style="margin-top: -40px;" />
<?php while($ac_fetch = mysql_fetch_array($qur_ac)){ ?>
<option value="<?php echo $ac_fetch['adclk_clicks']; ?>">
<?php echo $ac_fetch['adclk_clicks']; ?> clicks
</option>
<?php } ?>
</select>
<div id="chpln">Clicks: 0 clicks</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$('.select-box').change(function(){
var selectBoxClicks = $('.select-box').val();
$.ajax({url:"AjaxShowClickValue.php?selectBoxClicks="+selectBoxClicks,cache:false,success:function(result){
$('#chpln').html(result);
}});
});
</script>
Create a new page, namely AjaxShowClickValue.php.
AjaxShowClickValue.php (Make Sure, if you changing page name here. Then, change in <script></script> tag too. Both are related.)
<?
echo "Clicks: ".$_GET['selectBoxClicks']." clicks";
?>
II) Method - 2
<select name="" class='select-box'>
<option value="10">10 clicks</option>
<option value="20">20 clicks</option>
<option value="30">30 clicks</option>
<option value="40">40 clicks</option>
</select>
<div id="chpln">Clicks: 0 clicks</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$('.select-box').change(function(){
$("#chpln").text("Clicks: "+$(this).val()+" clicks");
});
</script>
use jQuery Ajax for making request to the php file..
and use on .change() rather than .click() for changing the dropdown value..
the code will be placed in JS file which make ajax call to the php file on your server..
The php file will takes some params (if any) and perform select query to the databases and return result in response.. in php use json_encode(data) for that..
These examples may also help:

You will find many other examples - Just Google It and understand the key concept!
Hope this helps.
