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">'.$errors['sendername'].'</span>'; } ?>
</div>
</div>
</div>
<input type="submit" value="Submit" name="submit">
</form>
<?php
}
?>
Try this.
<select name="name_title" class="name-title-input">
<option value="none" selected="selected">Select Title</option>
<option value="Mr" <? if(@$_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>
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 = ''; ?>
<?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($name_title == 'Ms') { ?>selected <?php } ?>>Ms</option>
</select>
I'll borrow @ThinkingWeb's code and tidy it up a bit. One of the great features of HTML tags is that you can line-break them, which makes for much more readable code. Each if
statement here gets its own line:
<select name="name_title" class="name-title-input">
<option value="none"
>Select Title</option>
<option value="Mr"
<?php if($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.
