I am developing web application for that i am using codeigniter-3 framework,i have one hardcoded dropdown in view file that is working fine as i expected.in my listing page one edit option is there i have passed the data from controller to the view file for binding the data for editing it's working fine except select dropdown can you please help me to fix the issue...?
<div class="form-group">
<label for="exampleInputName1">Movie Type</label>
<select name="m_type" id="" class="form-control">
<option value="">No Selected</option>
<option value="1">Horror</option>
<option value="2">Comedy</option>
<option value="3">Romance</option>
</select>
</div>
//it's working fine for Book Qty
<div class="form-group">
<label for="exampleInputName1">Book Quantity</label>
<input type="text" name="b_qty" class="form-control" value="<?php echo $res[0]->book_quantity; ?>" id="exampleInputName1" placeholder="">
</div>
dump
array(1) {
[0]=>
object(stdClass)#32 (13) {
["id"]=> '11'
["tank_type"]=> "1"
}
}
i want to bind the Horror in the edit page dropdown by default in this case.
Use selected attribute to do that or jQuery Code
jQuery('#m_type').val('1').trigger('change')
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="m_type" id="m_type" class="form-control">
<option value="">No Selected</option>
<option value="1">Horror</option>
<option value="2">Comedy</option>
<option value="3">Romance</option>
</select>
<select class="form-control" id="customer_id" name="customer_id">
<?php foreach ( $array as $item ){ ?>
<option value="<?php echo $item->id ?>"<?php echo($item->id=='1')?'selected':''; ?>><?php echo $item->label; ?></option>
<?php }?>
</select>

If I understood correctly, you want to suppress the data in a table with php in this way.
I wrote a mysqli query for you, it's $query variable.
$query = mysqli_query($db_connect,"SELECT * FROM tbl_variables");
Then I wrote this query with the while loop with the help of mysqli_fetch_object and read it line by line.
<?php
while ($row = mysqli_fetch_object($query)){
echo '
<option value="'?><?php echo $row->optionValue; ?><?php echo'">'?><?php echo $row->optionText; ?><?php echo'</option>
';
}
?>
All code parts;
<?php
$query = mysqli_query($db_connect,"SELECT * FROM tbl_variables");
?>
<div class="form-group">
<label for="val[]">Parameter K1</label>';
<select class="form-control" name="val[]">
<option value="" selected="" disabled="" hidden="">Choose one</option>
<?php
while ($row = mysqli_fetch_object($query)){
echo '
<option value="'?><?php echo $row->optionValue; ?><?php echo'">'?><?php echo $row->optionText; ?><?php echo'</option>
';
}
?>
</select>
</div>
I'm having some trouble passing the value of some HTML elements to PHP variable. I have a PHP web app where I give the users some drop down option. What I want to do is after the user has selected the option I give than to click on a button and make some calculations based on his/her selection.
I have tried using the POST and GET method but because I'm new to php I probably did it wrong. I also try with ids but no results.
Here is the HTML code
The 1st dropdown menu :
<div>
<select id="kleidwma" onchange="kleidwmata_change(this.value);kwdikos();ypsos();"
class="form-control selectpicker kleidwmata" data-size="10" data-
style="btn-white" name="guard_kleidwmata" required >
<option value="" > </option>
<option value="12">12 MS</option>
<option value="14">14 KETE</option>
<option value="15">15 ARRIKTON</option>
<option value="16">16 KETE</option>
<option value="22">22 KETE</option>
</select>
</div>
The 2nd dropdown menu :
<div>
<select id="sigkratisi" onchange="kwdikos()" name="sigkratisi"
class="form-control sigkratisi" required>
<option value="" ></option>
<option value="metalliki" >Μεταλλική</option>
<option value="xilogonia" >Ξυλογωνία</option>
</select>
</div>
Here is the button to be clicked after the selection has been made :
<div class="row" style="margin-top:20px; margin-left: 235px;">
<div class="col-md-7">
<input type="hidden" name="tmp_calculate" value="pending" />
<button onclick="calculate()" type="button" class="btn btn-success" >
<?php echo "Υπολογισμός";?></button>
</div>
</div>
And finally here is the function that is called :
function calculate()
{
$var1 = sigkratisi;
$var2 = kleidwma;
"code to be executed base on the var1 and var2"
}
I hope it's clear enough.
Thanks in advance for your time
you can use Forms
<form name="f" action="" method="POST">
<div>
<select id="kleidwma" name="variable"
class="form-control selectpicker kleidwmata" data-size="10" data-
style="btn-white" name="guard_kleidwmata" required >
<option value="" > </option>
<option value="12">12 MS</option>
<option value="14">14 KETE</option>
<option value="15">15 ARRIKTON</option>
<option value="16">16 KETE</option>
<option value="22">22 KETE</option>
</select>
<input type="submit" value="submit" />
</div>
</form>
in PHP
<?php
if(isset($_POST['variable']))
{
echo $_POST['variable'];
}
?>
When I select the all data of a product by it's product_id. and load product data in a form for an update. but here I cannot set selected drop-down list value in this case.
here, is my view
<form action="<?php //echo base_url().'admin_product/pro_update/'?>" method="post" class="form-horizontal">
<div class="control-group">
<label class="control-label">Title :</label>
<div class="controls">
<input type="text" class="span5 m-wrap" placeholder="Product title" name="title" value="<?php echo $item[0]['p_title']?>" />
<h6 style="color:red"><?php echo form_error('title')?></h6>
</div>
</div>
<div class="control-group">
<label class="control-label">Category :</label>
<div class="controls">
<select name="cat" id="cat">
<option value="">--Select Category--</option>
<?php foreach($cat as $c):?>
<option value="<?php echo $c->cat_id?>"><?php echo $c->cat_name;?>//selected set value here</option>
<?php endforeach;?>
</select>
<h6 style="color:red"><?php echo form_error('cat')?></h6>
</div>
</div>
here is my controller code,
public function pro_edit($id)
{
$p['item']=$this->ap->product_update($id);
$p['cat']=$this->ap->up_cat();
$p['color']=$this->ap->up_color();
$this->load->view('layouts/header',$p);
$this->load->view('admin/product_update',$p);
$this->load->view('layouts/footer',$p);
}
and model code,
public function product_update($id)
{
$this->db->select('p_title,p_description,p_category,p_stock_quantity,p_pprice,p_sprice,p_size_variant,cat_name,v_color,v_size,p_id');
$this->db->from('tbl_product');
$this->db->join('tbl_category','tbl_product.p_category=tbl_category.cat_id');
$this->db->join('tbl_variant','tbl_product.p_color_variant=tbl_variant.v_id');
$this->db->where('p_id',$id);
$query=$this->db->get();
return $query->result_array();
}
Assumptions
p_category is your category id
Code
<select name="cat" id="cat">
<option value="">--Select Category--</option>
<?php
foreach($cat as $c):?>
<option value="<?php echo $c->cat_id?>" <?php echo ($item[0]['p_category'] == $c->cat_id) ? 'selected' : '' ?>>
<?php echo $c->cat_name;?>
</option>
<?php
endforeach;
?>
</select>
Explain
Q - What this if do in above <?php echo ($item[0]['p_category'] == $c->cat_id) ? 'selected' : '' ?>
A - Assume $item[0]['p_category'] has value 2 so when ever $c->cat_id equesl to that value its print selected keyword
Ex:
<select>
<option value="1">aa</option>
<option value="2" selected>bb</option>
<option value="3">cc</option>
<option value="4">dd</option>
</select>
I am trying to get user selection from php form but instead of name I am getting id of elements. instead of ids I want to get names. Please help
here is the url
http://efinancec.com/d/drop4/index.php
and here is the code
<form action="../form/form1.php" method="post" enctype="multipart/form-data">
<div class="frmDronpDown">
<div class="row">
<label>Training:</label><br/>
<select name="training" id="training-list" class="demoInputBox" onChange="getCourse(this.value);">
<option value="">Select Training</option>
<?php
foreach($results as $training) {
?>
<option value="<?php echo $training["id"]; ?>"><?php echo $training["training"]; ?></option>
<?php
}
?>
</select>
</div>
<div class="row">
<label>Course:</label><br/>
<select name="course" id="course-list" class="demoInputBox" onChange="getCountry(this.value);">
<option value="">Select Course</option>
</select>
</div>
<div class="row">
<label>Country:</label><br/>
<select name="country" id="country-list" class="demoInputBox" onChange="getCity(this.value);">
<option value="">Select Country</option>
</select>
</div>
<div class="row">
<label>City:</label><br/>
<select name="city" id="city-list" class="demoInputBox" onChange="getDates(this.value);">
<option value="">Select City</option>
</select>
</div>
<div class="row">
<label>Dates:</label><br/>
<select name="dates" id="dates-list" class="demoInputBox" onChange="getPrice(this.value);">
<option value="">Select Dates</option>
</select>
</div>
<div class="row">
<label>Online Onsite Price:</label><br/>
<select name="price" id="price-list" class="demoInputBox">
<option value="">Select Online or Onsite</option>
</select>
</div>
<input id="submit" name="submit" type="submit" value="Submit">
</form>
and this is how I am getting the values from sql database
<?php
require_once("dbcontroller.php");
$db_handle = new DBController();
if(!empty($_POST["training_id"])) {
$query ="SELECT * FROM course WHERE training_id = '" . $_POST["training_id"] . "'";
$results = $db_handle->runQuery($query);
?>
<option value="">Select Course</option>
<?php
foreach($results as $course) {
?>
<option value="<?php echo $course["id"]; ?>"><?php echo $course["course"]; ?></option>
<?php
}
}
?>
Change this line:
onChange="getCourse(this.value);">
To this :
onChange="getCourse(this.text);">
You are passing id of the course as the value of dropdown and calling that value which is fine but you need to call the text of select option to get the course name.
I changed this.value to this.text as suggested and created the new page and it stoped working at all now it is not pulling the records from database except the first one. Here is the link
http://efinancec.com/d/drop4/index1.php
where as my earlier page is still working fine.
http://efinancec.com/d/drop4/index.php
I think I could not convey my problem earlier. My depended dropdown is working fine but when a user submits the form in the email I receive the ids instead of name. Thats the problem.
For example I myself made some selections on index.php and submitted form Here is the email I got
training: 1
course : 101
country: 1001
city: 5005
Basically I am getting the the respective ids instead of name.
I'am looking for a hide show script based on parentCatId and catId!
This is the div i try to hide and or show! div class="item-post-lot-area"
<div class="item-post-lot-area">
<label for="s_lotsize">
<?php _e('Lot Area', 'ctg_housing'); ?>
</label>
<div class="row collapse prefix-radius">
<div class="item-post-area-sign columns">
<span class="prefix"><?php echo osc_get_preference('metric','ctg_housing_theme'); ?></span>
</div>
<div class="item-post-area-number columns">
<input type="number" name="s_lotsize" id="s_lotsize" value="<?php if(isset($housingOut['s_lotsize'])) { echo $housingOut['s_lotsize'];} ?>" >
</div>
</div>
</div>
what i try!
item-post-lot-area field will all time show when loading the page! And will hide when selected the following parentCatId and catId
<option value="28">Vacation</option>
<select id="catId" name="catId" class="valid">
<option value="28">Select Subcategory</option>
<option value="29">Pension House</option>
<option value="30">Inn / Motel</option>
<option value="31">Hotel & Resort</option>
</option>
</select>
<select id="catId" name="catId" class="valid">
<option value="32">Select Subcategory</option>
<option value="33">Space</option>
<option value="34">Office</option>
<option value="35">BPO</option>
<option value="36">Economic</option>
</select>
Can someone explain me how to do this?
Thanks
You're probably looking along the lines of using .on("change") to run when the select element is changed. You can then check which value (if need be) has been selected, and then use $(".item-post-lot-area").hide() to hide the div.
$("#catId").on("change", function(){
$(".item-post-lot-area").hide();
});
