I want to get the product id called "product_id" through a alert in javaScript. But it gives "undefined" as the alert. I am getting data from a database.
Here is my PHP code.
$jsql_ae7 = mysql_query("select request_list.product_id from request_list where request_list.product_id='{$jrowa2['id']}' and request_list.email='$visit_email'") or die(mysql_error());
$jfeta7 = mysql_fetch_assoc($jsql_ae7);
Here is my HTML code.
<div class="col-sm-2">
<select id="<?php echo $jfeta7['product_id']; ?>" name="aformats" onchange="showFormat(this);">
<option value="<?php echo $jrowa2['formats']; ?>"><?php echo $jrowa2['formats']; ?></option>
<?php foreach($formats3 as $v3){ ?>
<?php if($v3 !== $jrowa2['formats']) { ?>
<option value="<?php echo $v3; ?>"><?php echo $v3; ?></option>
<?php } ?>
<?php } ?>
</select>
</div>
Here is my javaScript code.
var showFormat = function(dd) {
var format_select_id = $(this);
var product_id = format_select_id.attr("id");
alert(product_id);
};
Here is a screenshot of my page.
change with this
var showFormat = function(dd) {
var product_id = dd.id;
alert(product_id);
};
Why not just pass the product id directly?
<select id="<?php echo $jfeta7['product_id']; ?>" name="aformats" onchange="showFormat(<?php echo $jfeta7['product_id']; ?>);">
and your showFormat()
function showFormat(dd) {
alert(dd);
};

When the page is redirected, the language I chose in the box does not
appear. At first, whatever is available is chosen.
here is what I want to do: change option data
<select id='lang' class='btn btn-xs btn-primary icons-select2'>
<?php
$query_lang=mysqli_query($con, "SELECT * FROM tb_lang");
while($lang = mysqli_fetch_assoc($query_lang)){
if ($lang['durum']==1)}
?>
<option value = "<?php echo $lang['lang_fix']; ?>" data-min="_<?php echo $lang['lang_fix']; ?>"
data-icon="<?php echo $lang['lang_flag']; ?>">
<?php
echo strtoupper($lang['lang_fix']);
?>
</option>
<?php }} ?>
</select>
<script>
$(document).ready(function () {
$('body').on('change','#lang', function() {
var lang_id= $(this).val();
window.location.replace("index.php?lang="+lang_id);
});
});
</script>
First retrieve the lang sent over GET by
$lang_id = $_GET['lang'];
then check it against the data you are looping through
<option value = "<?php echo $lang['lang_fix']; ?>" data-min="_<?php echo $lang['lang_fix']; ?>" data-icon="<?php echo $lang['lang_flag']; ?>" <?php if ($lang_id == $lang['lang_fix']) echo "selected"; ?>>
making your code look like below, so the option you want to be selected will have the necessary selected attribute.
$lang_id = $_GET['lang'];
<select id='lang' class='btn btn-xs btn-primary icons-select2'>
<?php
$query_lang=mysqli_query($con, "SELECT * FROM tb_lang");
while($lang = mysqli_fetch_assoc($query_lang)){
if ($lang['durum']==1)}
?>
<option value = "<?php echo $lang['lang_fix']; ?>" data-min="_<?php echo $lang['lang_fix']; ?>" data-icon="<?php echo $lang['lang_flag']; ?>" <?php if ($lang_id == $lang['lang_fix']) echo "selected"; ?>>
<?php
echo strtoupper($lang['lang_fix']);
?>
</option>
<?php }} ?>
</select>
<script>
$(document).ready(function () {
$('body').on('change','#lang', function() {
var lang_id= $(this).val();
window.location.replace("index.php?lang="+lang_id);
});
});
</script>
I have a problem for the results to appear in my dropdown menu. For the dropdown menu I don't directly choose the type that matches the id that appears.
How to make the dropdown menu to appear according to the item ID?
This View.
label for="type">Type</label>
<select class="form-control" id="type_id" name="type_id">
<?php foreach($type as $types) : ?>
<?php if( $types == $barang['type_id']) : ?>
echo '<option value="<?php echo "$types->type_id"?>" selected><?php echo "$types->type_nama"?></option>';
<?php else : ?>
echo '<option value="<?php echo "$types->type_id"?>"><?php echo "$types->type_nama"?></option>';
<?php endif; ?>
<?php endforeach; ?>
</select>

public function getTypeQuery()
{
$this->db->order_by('type_id', 'asc');
$query = $this->db->get('type');
return $query->result();

{
return $this->db->get_where('barang', ['barang_id' => $id])->row_array();

Try change the views like this :
<label for="type">Type</label>
<select class="form-control" id="type_id" name="type_id">
<?php foreach($type as $types) : ?>
<?php if( $types->type_id == $barang['type_id']) : ?>
<option value="<?php echo $types->type_id ?>" selected><?php echo $types->type_nama ?></option>
<?php else : ?>
<option value="<?php echo $types->type_id ?>"><?php echo $types->type_nama ?></option>
<?php endif; ?>
<?php endforeach; ?>
</select>
So, I am fairly new to codeignitor and was hoping to get some help. Below I have my controller(Estimates.php), my model(Invoice_items_model.php) and my view(_add_edit_items.php). These are shortened versions as the full versions are pretty long.
What I am looking to do is have it so that when one of the select options is clicked it will then check the $suboption['non_compatible'] field for that suboption. If the suboption in any of the other select options matches that non_compatible field it will be disabled.
I found this post that I could probably work with but i'm not sure how to do an onchange event for dynamically generated selects.
Estimates.php
`public function estimate($id = ''){$data['platforms'] = $this->invoice_items_model->get_platforms();
$data['options'] = $this->invoice_items_model->get_options();
$data['suboptions'] = $this->invoice_items_model->get_suboptions();
$this->load->view('admin/estimates/_add_edit_items', $data);}`
Invoice_items_model.php
public function get_platforms()
{
$platforms = array();
$this->db->order_by('name', 'asc');
return $this->db->get('tblplatforms')->result_array();
}
public function get_options()
{
$options = array();
return $this->db->get('tblplatform_options')->result_array();
}
public function get_suboptions()
{
$suboptions = array();
return $this->db->get('tblplatform_suboptions')->result_array();
}
}'
_add_edit_items.php
<?php foreach($options as $option) { ?>
<tr>
<td></td>
<td><p><?php echo $option['name']; ;?>:</p></td>
<td>
<select name="<?php echo $option['name']; ?>" id="<?php echo $option['name']; ?>" rows="4" class="form-control">
<?php foreach($suboptions as $suboption) { ?>
<?php if($suboption['plat_option'] == $option['name']) { ?>
<option value="<?php echo $suboption['name']; ?>" id="<?php echo $suboption['name']; ?>"><?php echo $suboption['name']; ?></option>
<?php } ?>
<?php } ?>
</select>
</td>
</tr>
<?php } ?>
<tr>
keep your code as it is just change the event like this.
$(document).on("onChange", "your_selector", function() {
// your code
}
This is my Model

Combobox 1 linked to combobox 2, combobox 2 linked to combobox 3. when When I run it, only combo box 1 and 2 which have the data. I think the problem is on javascript. Need help, thank you. This is the pic of my combobox
I have a JavaScript code which works with HTML select tag.
$(function() {
$('#to_name').on('change',function() {
if( $(this).val()=="<?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?>") {
$('#to_designation').val('<?php echo $ceo_chunks[3];?>');
$('#dear_sir').val('<?php echo $ceo_chunks[0]?> <?php echo $ceo_last_name;?>') ;
if( $(this).val()=="<?php echo $liaison_one_chunks[0];?> <?php echo $liaison_one_chunks[1];?> <?php echo $liaison_one_chunks[2]?>") {
$('#to_designation').val('<?php echo $liaison_one_chunks[3]?>')
$('#dear_sir').val('<?php echo $liaison_one_chunks[0]?> <?php echo $liaison_one_last_name;?>')
$("#liaison_one").show()
$("#dear_liaison_one").show()
} else {
$("#ceo").hide()
$("#liaison_two").hide()
$("#dear_ceo").hide()
$("#dear_liaison_two").hide()
}
if( $(this).val()=="<?php echo $liaison_two_chunks[0];?> <?php echo $liaison_two_chunks[1];?> <?php echo $liaison_two_chunks[2]?>") {
$('#to_designation').val('<?php echo $liaison_two_chunks[3]?>')

$("#liaison_two").show()

} else {
$("#ceo").hide()
$("#liaison_one").hide()
$("#dear_ceo").hide()
$("#dear_liaison_one").hide()
}
};
});
});
and here is html code
<select name="to_name" id="to_name">
<option value="<?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?>"><?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?></option>

</div>
My function works very well for select tag but it's not working with input type text.
How can I fix that?
There is a closing bracket clearly missing for your first if statement.
Please close the bracket. There is no logical error in your code.
$(function() {
$('#to_name').on('change',function(){
if( $(this).val()=="<?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?>"){
$('#to_designation').val('<?php echo $ceo_chunks[3];?>')
$('#dear_sir').val('<?php echo $ceo_chunks[0]?> <?php echo $ceo_last_name;?>')
/*$("#ceo").show()
$("#dear_ceo").show()*/
//} ---uncomment this ---
also include a terminating semi-colon everytime you are calling a function. For example
if( $(this).val()=="<?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?>"){
$('#to_designation').val('<?php echo $ceo_chunks[3];?>');
$('#dear_sir').val('<?php echo $ceo_chunks[0]?> <?php echo $ceo_last_name;?>');
}
I suggest you use semicolons at the end of line (when appropriate). I know they are not mandatory but consider them as a good practice.
You also have a semicolon at the end of if-clause at the end. It's probably not braking anything but just in case...
Try replacing spaces with underscores (_).
For example:
<?php echo $ceo_chunks[0];?> <?php echo $ceo_chunks[1];?> <?php echo $ceo_chunks[2]?>
would become
<?php echo $ceo_chunks[0];?>_<?php echo $ceo_chunks[1];?>_<?php echo $ceo_chunks[2]?>
And check if you can alert the value of the changed input correctly.
