Sticky select with data from MySQL in PHP genereated form - php

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.

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.

code for fetching value to select option

I have select option. this option has multiple value from database. I want to update something from database, this value i want to update is exist on the select option I have.
this is my option code
$id = $_GET['update'];
$query = mysql_query("SELECT * FROM transaction where id = '$id'") or die ("could not search");
$count = mysql_num_rows($query);
while ($rows = mysql_fetch_array($query)) {
$id = $rows['id'];
$tranid = $rows['tranid'];
$trandate = $rows['trandate'];
$patientid = $rows['patientid'];
$transactiontype = $rows['transactiontype'];
$trandescription = $rows['trandescription'];
$tranquantity = $rows['tranquantity'];
$tranunitprice = $rows['tranunitprice'];
$tranamount =$rows['tranamount'];
$gettrandescription = $rows['trandescription'];
}
}
if (isset($_POST['selectmedicine'])) {
$gettrandescription=$_POST['medicineid'];
}
if (isset($_POST['selectroomquantity'])) {
$tranquantity=$_POST['quantity'];
}
?>
<script type="text/javascript">
$('#collapseone').collapseone({
toggle: true
});
<option value="<?php echo $trandescription; ?>" <?php if($trandescription==$gettrandescription){ echo "selected";} ?> ><?php echo $gettrandescription; ?></option>
<option value="<?php echo $tranquantity; ?>" <?php if($tranquantity==$tranquantity){ echo "selected";} ?> ><?php echo $tranquantity; ?></option>
this has value results, but i cant fetch this value to my existing select option.
If you want to "make that variable an array" as aldrin27 said, append [] to the name attribute of the select tag. The selected value of the option with name selectroomquantity will be available in your script as $_POST["selectroomquantity"] (this is the varible).
<select multiple name="selectroomquantity[]">
<option value="...">...</option>
</select>
It should only be necessary if multiple options can be selected however.
Also, there seems to be a typo:
<?php if($tranquantity==$tranquantity)
That check will always return true. It should probably be:
<?php if($tranquantity==$gettranquantity)

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>";
}
}

How to show selected value of dropdown list from database in php

How do I show the selected value of a dropdown list from my mysql database. The dropdown list is dependent to my Category dropdown list. These are the codes:
<?php $id = $_GET["id"];
if(!$pupcon){
die(mysql_error());
}
mysql_select_db($database_pupcon, $pupcon);
$getDropdown2 = mysql_query("select * from tblitemname where CategoryID = $id");
while($row = mysql_fetch_array($getDropdown2)){
echo "<option value=\"".$row["ItemID"]."\">".$row["Item_Name"]."</option>";
} ?>
Here are the codes for the first dropdown list (Category) which populates the Item Name dropdown.
<select name="Category" id="Category" class="field select large" onChange="loadXMLDoc(this.value);">
<?php do { ?>
<option value="<?php echo $row_Recordset1['CategoryID']?>"<?php if (!(strcmp($row_Recordset1['CategoryID'], $row_editRecordset['CategoryID']))) {echo "selected=\"selected\"";} ?>><?php echo $row_Recordset1['CategoryName']?></option>
<?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); $rows = mysql_num_rows($Recordset1); if($rows > 0) {
mysql_data_seek($Recordset1, 0);
$row_Recordset1 = mysql_fetch_assoc($Recordset1);}?>
</select>
While you're listing out the drop down options, you can check to see if the current ItemID matches the passed id value. If it matches, throw a selected="selected" in there. Try:
$selected = ($row['ItemID'] == $id);
echo "<option value=\"".$row["ItemID"]."\" ".($selected ? " selected=\"selected\"":"").">".$row["Item_Name"]."</option>";
EDIT
I tried to clean up the code some...not sure why you're using a do...while because $row_Recordset1 wouldn't be available on the first iteration.
<select name="Category" id="Category" class="field select large" onChange="loadXMLDoc(this.value);">
<?php
while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)) {
?>
<option value="<?php echo $row_Recordset1['CategoryID']; ?>"<?php if (!(strcmp($row_Recordset1['CategoryID'], $row_editRecordset['CategoryID']))) { echo " selected=\"selected\""; } ?>>
<?php echo $row_Recordset1['CategoryName']; ?>
</option>
<?php
}
?>
</select>
you can use this code inside while
$selected=$row["ItemID"]==$id ?'Selected':'';
echo "<option value=\"".$row["ItemID"]."\" {$selected} >".$row["Item_Name"]."</option>";;
