PHP 表单多个输入

Question

I am having issues with php and form handling. I want to be able to click a dropdown box(like you can do with a form in html, with the different options tags) in php, and allow the selection to take the designated value.

Here is what I have :

<input value="<?php echo isset($results['example']) ? $results['example']: ''; ?>" class="form-control" name="data[example]" placeholder="Example">

That populates with a place you can type in input text, which is accepted perfectly in post, but I do not want the user typing in data, only selecting from options, such as this html form does :

<form action="example.php">
<option value="11">apples</option>
<option value="12">bananas</option>
<option value="13">oranges</option>
</form>

Here is an edit using the data given :

<form>
                            <select name="example">
                                <option value="<?php echo isset($results['example']) ? $results['example']: ''; ?>">apples</option>
                                <option value="<?php echo isset($results['example']) ? $results['example']: ''; ?>">oranges</option>
                                <option value="<?php echo isset($results['example']) ? $results['example']: ''; ?>">bananas</option>
                            </select>
                        </form>

I did not add the action because it will be posted with other data, but did try both ways(with and without action="post.php") and it does not work...

Answer 1

Defining your options inside a select tag

<select>
<option value="11">apples</option>
<option value="12">bananas</option>
<option value="13">oranges</option>
</select>

Should give you in your post the position (value) of the selected item. Then in your php pass value to the selected items *11,12,13 = apples,bananas,oranges**

Hope it help

你需要一个<select name="name"> </select>围绕你的选项

Answer 3

So you are looking for a dropdown I guess:

<form action="example.php">
    <select name="fruit">
        <option value="1">Apple</option>
        <option value="2">Banana</option>
        <option value="3">Orange</option>
    </select>
</form>

On submiting the form you can get the value like: $_POST['fruit'] (in this case).

Answer 4

I think you need something like that

<form action="example.php">
    <select name="fruit">
        <option value="<?php echo isset($results['example']) ? $results['example']: ''; ?>">apples</option>
    </select>
</form>

Answer 5

I'd say the issue is not PHP, I think you just need to use the SELECT and OPTION form tags:

You are specifying an INPUT tag, which by definition allows the user to input data.

<form action="example.php">
 <select class="form-control" name="data[example]">
    <option value="<?php echo isset($results['example']) ? $results['example']: ''; ?>"">
</select>
</form>

Answer 6

use type="checkbox", so you can select one more

 <input type="checkbox" name="vehicle[]" value="Bike"> I have a bike<br> <input type="checkbox" name="vehicle[]" value="Car"> I have a car<br> <input type="checkbox" name="vehicle[]" value="Boat" checked> I have a boat<br>

in php

 <?php $vehicleArray=''; foreach($_POST['vehicle'] as $value) { $vehicleArray.=$value.','; } //output 'Bike,Car,Boat' ?>
