i have tried the above code i know the problem is with the "selected" please help me
You are almost close to the answer.
Some modifications and you are done.
You need to compare two values.
The value from database (selected value) and the value in loop.
Another suggestion is that we should not write any logic inside any
HTML tag.
HTMLs/Templates are just for printing output to screen.
We should first evaluate all conditions and then print HTML.
selected Reference
Change
echo '<option value="'. $row1['course_id'].'" selected="'. $row1['course_id'].'=='.$courseid.'">'.$row1['course_name'].'</option>';
To:
$selected = ($row1['course_id'] == $courseid) ? 'selected="selected"' : '';
echo '<option value="'. $row1['course_id'].'" ' . $selected . '>'.$row1['course_name'].'</option>';
Replace your while loop:
<?php
while($row1=$result->fetch_assoc())
{
$coursename=$row1['course_name'];
$courseid=$row['course_id'];
$paper=$row['paper_name'];
$paperdesc=$row['paper_description'];
$_SESSION['pid']=$row['paper_id'];
if($courseid == $row1['course_id']) {
echo '<option value="'. $row1['course_id'].'" selected>'.$row1['course_name'].'</option>';
} else {
echo '<option value="'. $row1['course_id'].'" >'.$row1['course_name'].'</option>';
}
}
?>
You can do it as following:
while($row1=$result->fetch_assoc())
{
$coursename=$row1['course_name'];
$courseid=$row['course_id'];
$paper=$row['paper_name'];
$paperdesc=$row['paper_description'];
$_SESSION['pid']=$row['paper_id'];
$selected="";
if($row['course_id']==$course_id)
{
$selected="selected";
}
echo '<option value="'. $row1['course_id'].'" $selected>'.$row1['course_name'].'</option>';
}
This makes your job done
while($row1=$result->fetch_assoc())
{
$coursename=$row1['course_name'];
$courseid=$row['course_id'];
$paper=$row['paper_name'];
$paperdesc=$row['paper_description'];
$_SESSION['pid']=$row['paper_id'];
echo "<option value = '{$row1['course_id']}'";
if ($courseid == $row1['course_id'])
echo "selected = 'selected'";
echo ">{$row1['course_name']}</option>";
}
Try this (use ternary operator inside option)
echo '<option value="'. $row1['course_id'].'" selected="'. $row1['course_id'].'=='.$courseid.'">'.$row1['course_name'].'</option>';
change into
<option value="<?= $row1['course_id'] ?>" <?= $row1['course_id']==$courseid? "selected":""?> > <?= $row1['course_name'] ?> </option>';

I have a question by these given information:
private function loadIntervallOptions($intervallid = 1, $intervallfactor=1){
echo "<select name='intervallfactor'>";
for($intervallnumber=1;$intervallnumber<10;$intervallnumber++){
$checked = "";
if($intervallnumber== $intervallfactor){
$checked = "selected";
}
echo "<option $checked>$intervallnumber</option>";
}
echo "</select>";
echo "<select name='intervallid'>";
for($i=0;$i<count($this->todo_intervall);$i++){
echo "<option value='{$this->todo_intervall[$i]->getintervallid()}' ";
if($this->todo_intervall[$i]->getIntervallid() == $intervallid){
echo "selected";
}
echo ">{$this->todo_intervall[$i]->getIntervall()}</option>";
}
echo "</select>";
}
What I want to do:
If intervallid=1 I want to hide the select 'intervallfactor'. Is this possible?
Thank you in advance!
EDIT:
I'm trying this but it won't work
$('.intervallid').change(function(e) {
if ($('.intervallid').val()==1){
$('.intervallfactor').attr('disabled','disabled');
}
else{
$('.intervallfactor').removeAttr('disabled');
}
});
$('.intervallid').trigger('change');
You are trying to reference the html element using a class name .intervallid which doesnt exist.
either you should use $('select[name="intervalid"]) or add an id to the select from php and, use that to reference the element.
PHP
echo "<select name='intervallid' id='intervall_id'>";
JS
$('#intervall_id').attr('disabled', 'true')
How can I retrieve selected value after form submision inside looped HTML select? I managed to solve the problem with manual if statements, but thats not dynamic.
I'm also storing previously submited value inside a cookie. I use self page form submit.
I managed to retrieve previous value from radio button:
<input type="radio" name="spol" value="moški" checked="checked" <?php if (isset($_POST['spol']) && $_POST['spol'] == 'moški') {
echo ' checked="checked"';
} ?>>
But can't find a way to do this inside foreach loop
<!---Cookie "keks" is storing previous submited string-->
<select name="status">
<?php
$_COOKIE['keks'];
$statusi = ["Dijak", "Študent", "Zaposlen", "Brezposelni"];
$counter= 0;
foreach ($statusi as $status) {
$counter++;
if ($counter == 2) {
echo "<option value=" . $status . " selected>" . $status . "</option>";
} else {
echo "<option value=" . $status . ">" . $status . "</option>";
}
}
?>
</select>
As stated in html comment, $_COOKIE['keks']; is storing the last value.
You might want to store that value into a variable or use it as is. and then, compare it against the current iteration of your loop.
$lastValue = $_COOKIE['keks'];
// some code
foreach ($statusi as $status)
{
if ($status == $lastValue)
// mark the option as selected
else
// don't mark it
}
This code in PHP always returns false.
I think it's a matter of how I compare values:
if (isset($_GET['materia']) and $_GET['materia']==$row['id_materia']){
echo'<option selected="selected" value="http://www.gonzalohll.com/pedidos.php?curso=1&?materia='.$row['id_materia'] .'">'. $row['materia'] .'</option>';}
else {
echo'<option value="http://www.gonzalohll.com/pedidos.php?curso=1&?materia='.$row['id_materia'] .'">'. $row['materia'] .'</option>';}
}
echo '</select>';
Any help on the subject is much apreciated.
You need to check the values for the variables that you are using, for see whats happening in your "if" statements.
For example, try this:
$id_materia = $row['id_materia'];
if (empty($id_materia)){
echo 'Incorrect value for id_materia';
} else {
echo 'id_materia: ' . $id_materia;
}
if (isset($_GET['materia'])){
echo ". Value for materia (GET): " . $_GET['materia'];
} else {
echo ". Materia (GET) not exists";
}
echo '<select>';
if (isset($_GET['materia']) && $_GET['materia'] == $row['id_materia']){
echo'<option selected="selected" value="http://www.gonzalohll.com/pedidos.php?curso=1&?materia='.$row['id_materia'] .'">'. $row['materia'] .'</option>';}
else {
echo'<option value="http://www.gonzalohll.com/pedidos.php?curso=1&?materia='.$row['id_materia'] .'">'. $row['materia'] .'</option>';}
}
echo '</select>';
I am trying to echo out "selected" on a value inside my array, within a foreach. If the form is false and my customer has already entered a particular value in my select, return it so he doesn't fill it again! That's what I am trying to do...
<?php
$marques = array('Word','Word1','Word20','Word46','Word9797');
foreach ($marques as $marque => $value)
{
if (isset($_POST['marque']) && $_POST['marque'] == $value[$_POST['marque']]) {
echo '<option value="'.$_POST["marque"].'">'.$value[$_POST["marque"]].'</option>';
}
echo '<option value="'.$marque.'">'.$value.'</option>';
}
?>
<?php
$marques = array('Word', 'Word1', 'Word20', 'Word46', 'Word9797');
foreach ($marques as $marque)
echo '<option value="'.$marque.'" '.(($marque == $_POST['marque']) ? 'selected' : '').'>'.$marque.'</option>';
?>
You mean this?
<?php
$marques = array('Word','Word1','Word20','Word46','Word9797');
foreach ($marques as $marque => $value) {
$setItSelected = '';
if (isset($_POST['marque']) && $_POST['marque'] == $marque) {
$setItSelected = 'selected';
}
echo '<option value="'.$marque.'" '.$setItSelected.'>'.$value.'</option>';
}
?>
Changing what's inside the value attribute doesn't make the item more or less selected. You need to add the selected attribute, see http://www.w3schools.com/tags/att_option_selected.asp
The output:ed html should look something like:
<option value="id" selected>some text</option>
<?php
$marques = array('Word','Word1','Word20','Word46','Word9797');
foreach ($marques as $marque)
{
if (isset($_POST['marque']) && $_POST['marque'] == $marque')
echo '<option value="'.$marque.'" selected>'.$marque.'</option>';
else
echo '<option value="'.$marque.'">'.$marque.'</option>';
}
?>
Your Array is one dimension, you can't use "=>"
For select option you must add the "selected" attribute too at your option tag
I am looking for some method to select a php combobox "<select>" based on results from mysql.
Actually I am working on a php form that will be used to edit existing values in mysql table. My first form will simply pass the id of the record to be edited, and this goes something like this Click to edit
Code on editCalendar.php is as follows:
<?php
include("dbpath.php");
$id = htmlspecialchars($_GET["id"]);
$sql="Select * from event_Date where eventid=" . $id;
$result=mysql_query($sql);
// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result)
{
$message = 'Invalid query: ' . mysql_error() . "\n";
$message .= 'Whole query: ' . $query;
die($message);
}
while($row = mysql_fetch_assoc($result))
{
$name=$row["EventTitle"];
$close=$row["OpenOrClose"];
$remarks=$row["Remarks"];
$date=$row["EventDate"];
$type=$row["Type"];
}
?>
The value obtained in $close will be used to select "SelectClosedOrOpen" on the same form, i.e. the user will get pre selected option from the populated list.
<select id="SelectClosedOrOpen">
<option value="3">Select</option>
<option value="0">Open</option>
<option value="1">Closed</option>
</select>
Means, if $close has 0, then <option value="0">Open</option> must be selected else if $close has 1 then <option value="1">Closed</option> should be automatically selected on formload.
You'll just need to write the selected attribute in there. Try this
<select id="SelectClosedOrOpen">
<option value="3" <?php echo ($close == 3) ? 'selected="selected"': ''; ?>>Select</option>
<option value="0" <?php echo ($close == 0) ? 'selected="selected"': ''; ?>>Open</option>
<option value="1" <?php echo ($close == 1) ? 'selected="selected"': ''; ?>>Closed</option>
</select>
I created this function some years back. I hope it helps you.
It basically requires an array of your options and the value of the option to be pre-selected. It returns the OPTIONS for your select, so you still have to create the SELECT tags, which allows you to customise the ID, JS etc..
function drop_down_box_options_from_array($choices,$default="")
{
$output= '';
// $choices is contructed using $choices[]=array("value","Displayed Choice");
while (list ($key, $val) = each ($choices))
{
$output.= '<option value="';
$output.= $choices[$key][0];
if ($default==$choices[$key][0])
{
$output.= '" selected="selected" >';
}
else
{
$output.= '">';
}
$output.= $choices[$key][1];
$output.= '</option>';
$output.= "\n";
}
return $output;
}
Using your scenario:
<select id="SelectClosedOrOpen" name="OpenOrClose">
<?php
// defined here for clarity, but can be defined earlier ie in a config file
$choices[]=array('3', 'Select');
$choices[]=array('0', 'Open');
$choices[]=array('1', 'Closed');
echo drop_down_box_options_from_array($choices, $row['OpenOrClose']);
?>
</select>
