Sticky drop down box issue in php - php

I am trying to create a sticky drop down option box. but every time I click the submit button, the value doesn't carry over. It changes.
What am I doing wrong?
<select name=person >
<option value="NULL">Choose a person</option>';
<?php $dbc = getDBC ();
$result = $dbc->query('SELECT * from person');
while ($row = $result->fetch_assoc()) {
echo "<option value=\"$row[ID]\"";
if (isset($_POST['person']) && ($_POST['person'] == $row[ID])) {
echo 'selected="selected"';
}
echo ">($row[ID]) &nbsp $row[FIRST_NAME] &nbsp $row[LAST_NAME]</option>\n";
}
?>
</select>

Try below code i made some syntax changes changes. and also you can optimize it using where condition SELECT * from person where id = $_POST['person']
<select name=person >
<option value="NULL">Choose a person</option>';
<?php
$dbc = getDBC ();
$result = $dbc->query('SELECT * from person');
while ($row = $result->fetch_assoc()) {
echo "<option value=\"$row['ID']\"";
if (isset($_POST['person']) && $_POST['person'] == $row['ID']) {
echo 'selected="selected"';
}
echo ">($row['ID']) &nbsp $row['FIRST_NAME'] &nbsp $row['LAST_NAME']</option>\n";
}
?>
</select>

Duple select from database in same table but diffent proposes

First option of select must be the name referring to the ID. The remaining select options are the remaining names
<select class="input" name="client_id">
<?php
$sel_client_detail="Select * from client WHERE client_id=".$id."";
$result_detail = mysqli_query($con,$sel_client_detail);
while($new_record_row = mysqli_fetch_assoc($result_detail)) { ?>
<option selected><?php echo $row['nome'];?></option>
<?php };?>
<?php
$sel_client="Select * from client";
$result = mysqli_query($con,$sel_client);
?>
<option>-----------</option>
<?php while($new_record_row = mysqli_fetch_assoc($result)) { ?>
<option><?php echo $new_record_row['nome'];?></option>
<?php };?>
</select>
Output:
<select>
<option selected> Izzi (current ID name)</option>
<option> ____________</option>
<option> Other existing clients</option>
<option> Other existing clients</option>
<option> Other existing clients</option>
<option> Other existing clients</option>
</select>
If you want the user to be first in your option list just run the query once and build the HTML parts in 2 seperate strings. Then once the loop is complete put them together and echo them
<?php
echo '<select class="input" name="client_id">';
$itsme = '';
$others = '<option>-----------</option>';
$sql = "Select * from client";
$result = $con->query($sql);
while($row = $result->fetch_assoc()){
if ( $id == $row['id'] ) {
$itsme = "<option selected='selected'>$new_record_row[nome]</option>";
} else {
$others += "<option>$new_record_row[nome]</option>";
}
}
// put the option tags together in the order you specified
echo $itsme . $others . '</select>';
Here's a different, but more conventional, approach to this common scenario:
Why not just make the chosen ID selected when you get to it in the list? Then it will still show to the user first. It's more efficient than having two separate queries.
Like this:
<select class="input" name="client_id">
<?php
$sel_client="Select * from client";
$result = mysqli_query($con,$sel_client);
?>
<option>-----------</option>
<?php while($new_record_row = mysqli_fetch_assoc($result)) { ?>
<option <?php echo ($new_record_row["client_id"] == $id ? "selected": ""); ?> ><?php echo $new_record_row['nome'];?></option>
<?php };?>
</select>

PHP - Edit page , How to set default dropdownlist that have option from MySQL?

I know only this method. this method is assume that you know the values in all <option>
<select name="agama" id="agama">
<option value="Islam"<?php if ($rows['agama'] === 'Islam') echo ' selected="selected"'>Islam</option>
<option value="Khatolik"<?php if ($rows['agama'] === 'Khatolik') echo ' selected="selected"'>Khatolik</option>
<option value="Protestan"<?php if ($rows['agama'] === 'Protestan') echo ' selected="selected"'>Protestan</option>
<option value="Hindu"<?php if ($rows['agama'] === 'Hindu') echo ' selected="selected"'>Hindu</option>
<option value="Buddha"<?php if ($rows['agama'] === 'Buddha') echo ' selected="selected"'>Buddha</option>
<option value="Lain-Lain"<?php if ($rows['agama'] === 'Lain-Lain') echo ' selected="selected"'>Lain-Lain</option>
</select>
.... the above code is example from other people not mine.
but My case is the <option> is select from database too.
I have 2 table, oav_event and oav_album
the oav_album has foreign key (event_id) from oav_event table
I want to check if row['event_id'] from oav_album table is equal to option value (from oav_event table) if true, then set selected="selected"
while($row = mysqli_fetch_assoc($result)) { ?>
<option value="<?php echo $row['event_id']; ?>" >Event: <?php echo $row['event_date']; ?> </option>
<?php } ?>
the option will change depend on change in database table, so I don't know the value in option. How should I do?
<select name="event_id">
<?php
$sql = "SELECT * FROM oav_event";
$result = mysqli_query($conn, $sql);
while($row = mysqli_fetch_assoc($result)) {
$selected = "";
if($row['event_id'] == $Yourmatchvalue)
{
$selected = "selected";
}
?>
<option value="<?php echo $row['event_id']; ?>" selected="<?php echo $selected; ?>" >Event: <?php echo $row['event_date']; ?> </option>
<?php } ?>
</select>
may this helps your. you need to replace $Yourmatchvalue variable with your variable.
You can use $_GET as the method on your form and pass the id of the record using it:
while($row = mysqli_fetch_assoc($result)) {
if (!empty($_GET['event_id']) && $row['event_id'] == $_GET['event_id']) {
$selected = 'selected = "selected"';
} else {
$selected = '';
}
echo '<option '.$selected.' value="'.$row["event_id"].'">'.$row["event_date"].'</option>';
}
Here is a solution,
$selected_value = 'Hindu'; // This will come from database
Change option tag with this
<option value="<?php echo $row['event_id']; ?>" <?php echo ($row['event_id'] == $selected_value) ? 'selected="selected"' : ''; ?> >Event: <?php echo $row['event_date']; ?> </option>
Create one function which will create options list like this:
function setDropdownValue($selectQueue_list,$selectedVal)
{
$queueVal = '';
$selectQueue_list_res=$db->query($selectQueue_list);
while($selectQueue_list_res_row=$db->fetchByAssoc($selectQueue_list_res))
{
$val = $selectQueue_list_res_row['id'];
$name = $selectQueue_list_res_row['name'];
if($val == $selectedVal)
{
$queueVal .= "<option value='$val' selected='selected' label='$name'>$name</option>";
}
else
{
$queueVal .= "<option value='$val' label='$name'>$name</option>";
}
}
return $queueVal;
}
Then create a query:
$get_value_query="SELECT id, name FROM table";
$dropdown_selected_value = !empty($dropdown_value) ? $dropdown_value: ''; // Pass value which you want to be selected in dropdown
Then call this function:
$dropdown_options = setDropdownValue($get_value_query, $dropdown_selected_value);
Later when you get dropdown options in $dropdown_options, use jquery to populate the dropdown, like this:
$('#dropdown_select_id').html("$dropdown_options");
Give it a try, and let me know.

Sticky select with data from MySQL in PHP genereated form

I have a sticky select form, which gets the data for the options from MySQL. The form should display "Select Type" if no form was submitted (this works). Then I tried to make it sticky. My idea was to compare the $_POST['type'] with the data from MySQL and if its the same it should echo selected.
The $_POST['type'] was working perfectly when I tried to echo it, also the options from the MySQL DB are working.
I feel like I'm close to the solution, but I'm missing something. Any ideas?
<select type="text" name="type" id="type" class="form-control input-lg">
<option value="" disabled <?php if(!isset($_POST['submit'])){ echo "selected";} ?> >Select type</option>
<?php
$result = mysql_query("select * from type");
while ($row = mysql_fetch_assoc($result))
{
$type[] = $row;
}
$count = count($type);
for ($i = 0; $i < $count; $i++)
{
$selected = $_POST['type'];
echo "<option";
if($selected === $type[$i] ){
echo "selected";
}
echo ">";
echo $type[$i]['type'];
echo '</option>';
}
?>
</select>
Change the line echo "selected"; to echo " selected ";
It will currently echo <optionselected> on selected option which is malformed.

show selected value from dropdown

Hi i have been working on a form wherein there's a dropdown menu and it's values are from the database. My problem is it doesnt show the value selected after submitting the form. what maybe the problem?
<select name="professional" />
<option value="">Choose one</option>
<?php
$result2 = mysql_query("SELECT * FROM professional");
while($row2 = mysql_fetch_array($result2))
{
$prc = $row2['name'];
$prof = $row2['prcno'] ."\t"."|\t". $row2['name'] ."\t"."|\t".$row2['profession'];
echo "<option value ='$prc'>$prof</option>";
}
?>
</select>
<select name="professional" disabled/>
<option value="">Choose one</option>
<?php
$result2 = mysql_query("SELECT * FROM professional");
$i=0;
while($row2 = mysql_fetch_array($result2))
{
$prc = $row2['name'];
$p1[$i] = $prc;
$prof = $row2['prcno'] ."\t"."|\t". $row2['name'] ."\t"."|\t".$row2['profession'];
$p2[$i] = $prof;
if($_POST['professional'] == $p1[$i])
{
echo "<option selected value ='$p1[$i]'>$p2[$i]</option>";
}
else
{
echo "<option value ='$p1[$i]'>$p2[$i]</option>";
}
}
?>
</select>
It seems to me, you're not incrementing $i, so you keep overwriting $p1[0] and $p2[0] in each iteration of the while-loop.
So add $i++ at the beginning or the end of your loop - or drop the whole use of these to arrays ($p1 and $p2) and use $prc and $prof just as you do in the first code-block - or do you need them for something?
Another thing, try removing the space between value and ='$p1[$i]' - but I'm not sure if that's a problem.
Try
selected="selected"
in stead of
selected
change these lines to
echo "<option selected value ='<?php echo $p1[$i]; ?>'><?php echo $p2[$i]; ?></option>";
and do not forget to increment your $i too
Hope it will help :)

PHP : Get the value of Dropdown and pass it to another dropdown

I have a problem right now [PHP]. I have a dropdown and its loading my database for the first page, when I proceed to the next page it also have a dropdown where its also loading the my database and also I can get the value of my dropdown in the first page using an echo only.
This is the scenario:
I choose in the dropdown first page the "Letter A" and when I click the button it will proceed to the next page. The dropdown in the second page loaded the items in the database but instead of "-select-" is the first index in the dropdown I want is "Letter A" will be the first index.
This is my code in first page for drowdown:
<select name="id">
<option value="" >- select -</option>
<?php
include 'connect.php';
$q = mysql_query("select fldNetname from tblnetwork");
while ($row1 = mysql_fetch_array($q))
{
echo "<option value='".$row1[fldNetname]."'>".$row1[fldNetname]."</option>";
}
?>
</select>
and this is my code in second page for dropdown:
if ($get_ID != "")
{
echo "<br/>";
echo $get_ID;
//echo "show()";
}
else
{
echo "No Network Selected";
echo "<br/>";
//echo "hide()";
}
?>
<option value="">- select -</option>
<?php
include 'connect.php';
$q = mysql_query("select fldNetname from tblnetwork");
while ($row1 = mysql_fetch_array($q))
{
echo "<option value='".$row1[fldNetname]."'>".$row1[fldNetname]."</option>";
}
?>
</select>
Thanks in advance!
On your second page, you need to check whether the value is the same as the one you received from the first page:
echo "<option value='".$row1[fldNetname]."' " . (($row1[fldNetname] == $get_id)?"selected":"") . ">".$row1[fldNetname]."</option>";
if $get_ID, is actually your $_GET['id'] value, then just do...
while ($row1 = mysql_fetch_array($q))
{
echo "<option value='".$row1['fldNetname']."'";
if($row1['fldNetname']==$get_ID){echo "selected='selected'";}
echo ">".$row1['fldNetname']."</option>";
}
Or as one line...
while ($row1 = mysql_fetch_array($q))
{
echo "<option value='".$row1['fldNetname']."' " . (($row1['fldNetname'] == $get_ID)?"selected='selected'":"") . ">".$row1'[fldNetname']."</option>"
}
Have you tried?
changing (on the second page)
<option value="">- select -</option>
to
<option value="<?php echo $yourVar; ?>"><?php echo $yourVar; ?></option>
Then in the while loop, skip the value selected to prevent a duplicate choice.
Something like:
while ($row1 = mysql_fetch_array($q))
{
if($yourVar != $row1[fldNetname]){
echo "<option value='".$row1[fldNetname]."'>".$row1[fldNetname]."</option>";
}
}
