I have problems with this particular form, i need first to select a value and then to submit the form. Submit form works good, however the default selection value in all browsers is selected and it is Acceptable, except in IE where no default selection value is selected. In IE there is nothing selected by default.
How do I fix this?
Picture of the problem :
:
<select name="formQuality" id="formQuality" value="acceptable">
<option value="acceptable">Acceptable</option>
<option value="good">Good</option>
<option value="better">Better</option>
<option value="excellent">Excellent</option>
<option value="best">Best</option>
</select>
<?php
if(isset($_POST['SubmitButton'])){ //check if form was submitted
$input = $_POST['inputText']; //get input text
$varQuality = $_POST['formQuality'];
$message = "Success! You entered: ".$input;
}
?>
<br>
<form action="" method="post">
<h1>Choose Quality:</h1>
<?php
$thequa = htmlspecialchars($_POST['formQuality']);
?>
<select name="formQuality" id="formQuality" value="<?php echo $thequa;?>">
<option <?php if ($thequa1 == 'acceptable') { ?>selected="true" <?php }; ?> value="acceptable">Acceptable</option>
<option selected="true" value="acceptable">Acceptable</option>
<option <?php if ($_POST['formQuality'] == 'good') { ?>selected="true" <?php }; ?> value="good">Good</option>
<option <?php if ($_POST['formQuality'] == 'better') { ?>selected="true" <?php }; ?> value="better">Better</option>
<option <?php if ($_POST['formQuality'] == 'excelent') { ?>selected="true" <?php }; ?> value="excellent">Excellent</option>
<option <?php if ($_POST['formQuality'] == 'best') { ?>selected="true" <?php }; ?> value="best">Best</option>
</select>
<textarea name="inputText" cols="100" rows="20" style="border:solid 1px orange;"><?php echo $thetext;?></textarea>
<p>
<input type="submit" value="Rewrite" name="SubmitButton"/>
</form>
The intended way to preselect an option is setting the selected attribute on the option element, rather than adding a value attribute to the select field.
<select name="formQuality" id="formQuality">
<option value="acceptable" selected>Acceptable</option>
<option value="good">Good</option>
<option value="better">Better</option>
<option value="excellent">Excellent</option>
<option value="best">Best</option>
</select>
This produces the expected result in all browsers, including IE.
Use selected="selected"
Like,
<option value="My Default" selected="selected">
to make an option as default selected value. This works in all browsers.

Here's the process I want to realize:
1.on index page, select one option from the list of items;
2.submit form,directing to the index page ;
3.select label showing the default value which equals what I chose in step 1.
e.g.
<html>
<select>
<option value="1">1<option/>
<option value="2">2<option/>
<option value="3">3<option/>
</select>
</html>
On index page if I chose 1 ,and submit it and the page is submitted to itself(the index page).Now,on the index page, <option value="1">1<option/> is selected by default.
I don't know which correct direction I should go and I haven't found any solutions from the Internet yet.Anybody has any ideas??
Thanks a lot!
Using PHP function and javascript onchange:
<html>
<?php
if (isset($_POST["myselect"])) {
$myselect = $_POST["myselect"];
}
else {
$myselect = 1;
}
function isselected(A,B) {
if ($A == $B){
return "selected";
}
else{
return false;
}
}
?>
<form action="index.php" method="post">
<select name="myselect" onchange="this.form.submit();">
<option value="1" <?php echo isselected(1,$myselect) ?> >1<option/>
<option value="2" <?php echo isselected(2,$myselect) ?> >2<option/>
<option value="3" <?php echo isselected(3,$myselect) ?> >3<option/>
</select>
</form>
</html>
1st : Name attribute is must for form elements .otherwise element value would not passed to server.
2nd : Check the post value and add the selected attribute for that option like below .
<select name="select1">
<option value="">Select</option>
<option value="1" <?php echo (isset($_POST['select1']) && $_POST['select1']==1 )? 'selected':''; ?>>1</option>
<option value="2" <?php echo (isset($_POST['select1']) && $_POST['select1']==2 )? 'selected':''; ?>>2</option>
<option value="3" <?php echo (isset($_POST['select1']) && $_POST['select1']==3 )? 'selected':''; ?>>3</option>
</select>
coudn't understand your question quite well but..If you want to select any other value by default, once the page comes back to the index page, you will have to send the selected value back to the index page.
<html>
<select>
<option value="1">1<option/>
<option value="2" selected="selected">2<option/>
<option value="3">3<option/>
</select>
</html>
The above would select option 2, so you just have to set it accordingly.

Take a look at this SO question: How to check if an option is selected?
Using what is suggested in that link, add an alert with whatever message you want if no option has been selected.
There are new lines of code but have certain changes for better understanding for you and test.
HTML code
<div class="members-wrap-vehicle">
<label>Vehicle</label>
<select name="reservation[vehicle]">
<option value="0">Select</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</div>
<div class="members-vehicle-list">
<div class="members-wrap-adult">
<label>Cars</label>
<select name="reservation[cars]">
<option value="0">Select</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</div>
<div class="members-wrap-child">
<label>Caravans</label>
<select name="reservation[caravans]">
<option value="0">Select</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</div>
<div class="members-wrap-infant">
<label>Buses</label>
<select name="reservation[buses]">
<option value="0">Select</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
</div>
</div>
jQuery Code
$(function(){
$('.members-wrap-vehicle select').change(function(){
var cars = $('.members-wrap-adult select option:selected').val();
var caravans = $('.members-wrap-child select option:selected').val();
var buses = $('.members-wrap-infant select option:selected').val();
if ( cars == 0 || caravans == 0 || buses == 0 ){
alert('please select any of cars or caravans or buses');
}
});
});
Hope this works for you. THank YOu
This should work but there are some caveats. You have to change your <select> element names to ids (id = 'xxx'). Also, this function assumes that the number of vehicles in the sub menus totals the number in the vehicles menu. Please let me know if you need anything further! Cheers
$('#BUTTON_ID').on('click', function() {
var vehicle = $('#reservation[vehicle]').val();
var cars = $('#reservation[cars]').val();
var caravans = $('#reservation[caravans]').val();
var buses = $('#reservation[buses]').val();
if (vehicle == (cars + caravans + buses)) {
//do something
} else {
//error message
alert('Error has occurred.');
};
});

catid loads some values from databases, and catid1 have some manual entries, few of them are same and few are different. but i want is when i will select catid1 value from list like "abc" then catid value should be changed to same as catid1 "abc"
i have tried some different ways but can't resolve this, any one please suggest either this could be possible or not.
<div class="col-md-4">
<div class="form-group">
<label for="catId"><?php echo $categoryField; ?></label>

<div class="col-md-4">

sample code which i have tried is as below as well but it's not working in my case.
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
var selects = document.querySelectorAll('select[name="dropdown[]"]');
selects[0].addEventListener('change', function () {
for (var i = 0; i < selects.length; i++) {
selects[i].value = selects[0].value;
}
});
You forgot your script tags in the second example:
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
<select name="dropdown[]">
<option value="1">Sony</option>
<option value="2">Nintendo</option>
<option value="3">Microsoft</option>
</select>
<script language="javascript">
var selects = document.querySelectorAll('select[name="dropdown[]"]');
selects[0].addEventListener('change', function () {
for (var i = 0; i < selects.length; i++) {
selects[i].value = selects[0].value;
}
});
</script>

Yes you can do it by javascript or Jquery. Its easier in Jquery like
function qt() {
var catId1Val = $('#catId1 :selected').val();
$("#catId> option").each(function() {
if (this.value == catId1Val)
$("#catId select").val(this.value);
});
}
Check out the following jQuery method:

I have designed option selection in html.
<select>
<option value="e">Electronics</option>
<option value="c">Clothing & Accessories</option>
</select>
I want when i select Electronics. the electronic value should be assign to a php variable.when i select Clothing & Accessories. Clothing & Accessories should be assign to a php variable
Use the select inside a form. And get the selected option by POST method.
<form action="#" method="POST">
<select name="selection">
<option value="e">Electronics</option>
<option value="c">Clothing & Accessories</option>
</select>
</form>
<?php
$value = $_POST['selection']; // this $value variable contains the value of selected value.
?>
Please try this:
<?php
if (!empty($_GET['dropdown'])) {
$dropdownval = $_GET['dropdown'];
} else {
$dropdownval = 1;
}
?>
<form method="get" action="xyz.php">
<select name="dropdown" >
<option value="e" <?php if ($dropdownval=="e") echo 'selected="selected"'; ?>>Electronics </option>;
<option value="c" <?php if ($dropdownval=="c") echo 'selected="selected"'; ?>>Clothing & Accessories</option>;
</select>
<input type="submit" name="submit" value="Submit Form" />
</form>
I am creating a very simple form with a dropdown menu and a text filed.
It shows the errors if the form has empty field during the submission.
I want to show the filled values after the form submission if there is any error.
It works on text field as I expected.
Ex: If fill the name and submit the form without filling the title dropdown menu, it showing the name I typed on the filed during the the error is appeared.
But how can I do that for dropdown menu also?
Ex: If I select the title drop down menu and submit the form without filling name field, it should show the selected title dropdown value during the the error is appeared.
how can I do that?
here is my code and it's a wordpress site:
<?PHP
$errors = array();
if($_POST["submit"]) {
$name_title = $_POST["name_title"];
$sender = $_POST["sendername"];
//Check the name title that it is selected or none.
if($name_title === none){
//if selected is none, add error to $errors array.
$errors['name_title'] = "Please select the title of your name!";
}
if(empty($sender)){
//Blank string, add error to $errors array.
$errors['sendername'] = "Please enter your name!";
}
// sending form
if(empty($errors)){
$mail_sent = wp_mail( $to, $subject, $mailBody, $headers );
}
}
if ($mail_sent) {
?>
<h1 style="color: #007f00;">Request sent.</h1>
<?php
} else {
?>
<form id="" name="" action="<?php echo get_permalink(); ?>" method="post">
<div class="label-input-wrapper">
<div class="form-label">Title</div>
<div class="form-input">
<select name="name_title" class="name-title-input">
<option value="none" selected="selected">Select Title</option>
<option value="Mr">Mr</option>
<option value="Mrs">Mrs</option>
<option value="Miss">Miss</option>
<option value="4">Ms</option>
</select>
<div class="error-msg">
<?php if(isset($errors['name_title'])) { echo '<span style="color: red">'.$errors['name_title'].'</span>'; } ?>
</div>
</div>
</div>
<div class="label-input-wrapper">
<div class="form-label">Name</div>
<div class="form-input">
<input type="text" name="sendername" value="<?PHP if(!empty($errors)) { echo $sender;} ?>" />
<div class="error-msg">
<?php if(isset($errors['sendername'])) { echo '<span style="color: red">'.$errors['sendername'].'</span>'; } ?>
</div>
</div>
</div>
<input type="submit" value="Submit" name="submit">
</form>
<?php
}
?>
although the answer by #CKocer can also work but I like to use variables instead and using $_POST in HTML and also more readable
In declare $name_title out side of if($_POST) and can do it like this <?php $name_title = ''; ?>
For Drop Down code change like this
<select name="name_title" class="name-title-input">
<option value="none" selected="selected">Select Title</option>
<option value="Mr" <?php if($name_title == 'Mr') { ?> selected <?php } ?>>Mr</option>
<option value="Mrs" <?php if($name_title == 'Mrs') { ?> selected <?php } ?>>Mrs</option>
<option value="Miss" <?php if($name_title == 'Miss') { ?> selected <?php }
?>>Miss</option>
<option value="4" <?php if($name_title == 'Ms') { ?>selected <?php } ?>>Ms</option>
</select>
Try this.
<select name="name_title" class="name-title-input">
<option value="none" selected="selected">Select Title</option>
<option value="Mr" <? if(#$_POST['name_title'] == 'Mr') { echo 'selected = \"selected\"'; } ?>>Mr</option>
<option value="Mrs" <? if(#$_POST['name_title'] == 'Mrs') { echo 'selected = \"selected\"'; } ?>>Mrs</option>
<option value="Miss" <? if(#$_POST['name_title'] == 'Miss') { echo 'selected = \"selected\"'; } ?>>Miss</option>
<option value="4" <? if(#$_POST['name_title'] == 'Ms') { echo 'selected = \"selected\"'; } ?>>Ms</option>
</select>
I'll borrow #ThinkingWeb's code and tidy it up a bit. One of the great features of HTML tags is that you can line-break them, which makes for much more readable code. Each if statement here gets its own line:
<select name="name_title" class="name-title-input">
<option value="none"
>Select Title</option>
<option value="Mr"
<?php if($name_title == 'Mr'): ?> selected="selected" <?php endif ?>
>Mr</option>
<option value="Mrs"
<?php if($name_title == 'Mrs'): ?> selected="selected" <?php endif ?>
>Mrs</option>
<option value="Miss"
<?php if($name_title == 'Miss'): ?> selected="selected" <?php endif ?>
>Miss</option>
<option value="4"
<?php if($name_title == 'Ms'): ?> selected="selected" <?php endif ?>
>Ms</option>
</select>
I've dropped the selected="selected" in the first option - this will select automatically if there is no explicit selection, and you don't want more than one! I've switched all the selections to use the attribute="value" format, though I don't think it's mandatory for HTML.
I've used the colon form of the if statement too - for HTML I find it preferable to the brace approach.
