Laravel4:带有图像选择器的表单 [英] Laravel4: Form with image-picker
问题描述
在使用Bootstrap + Laravel4的站点中. 在表单中，用户可以单击一些图像来选择它. 这是通过一个不错的JQuery插件完成的: http://rvera.github.io/image-picker/
In a site working with Bootstrap + Laravel4. In a form, there are some images that the user can click to select it. It is done with a nice JQuery plugin: http://rvera.github.io/image-picker/
现在它是用html编写的，并且可以正常工作:
Right now it is written in html and it is working:
<label><span><i class="icon-check"></i></span> Click on a room to select it</label>
<select name="rooms[]" multiple="multiple" class="image-picker show-html">
<option value=""></option>
<option name="1room" data-img-src="assets/img/rooms/singleRoom.jpg" value="Single room">Single room</option>
<option name="2room" data-img-src="assets/img/rooms/2room.jpg" value="Double room">Double room</option>
</select>
我不需要在Laravel4中重写所有这些标记. 但是我需要一件事:我必须添加到Input :: old('inputName')来保留值，以防发生验证错误. 那很重要. 我尝试这样做: -将单个选项的值设置为:{{'Single room'，Input :: old('1room')}} -将选择的值设置为{{Input :: old('rooms []')}} 但是他们都不在工作. 它没有错误，但是没有保留原始值.
I do not need to rewrite all these markups in Laravel4. But i need one thing: I have to add to Input::old('inputName') to retain the values in case of validation errors. That is very important. I have tried doing this: - set value of the single options to: {{ 'Single room', Input::old('1room') }} - set the value of the select to {{ Input::old('rooms[]') }} But none of them is working. It gives no errors, but the original value is not retained.
有人知道我该怎么办?
非常感谢！
在页面顶部打印出Input :: old()的值，实际上保留了房间的值:
Printing out the value of Input::old() at the top of the page, the value for rooms are actually retained:
array (size=8)
'rooms' =>
array (size=2)
0 => string 'Single room' (length=11)
1 => string 'Double room' (length=11)
'arrival' => string '13/11/2013' (length=10)
'outgoing' => string '11/11/2013' (length=10)
'name' => string 'name' (length=4)
'email' => string 'email' (length=5)
'phone' => string '9999999999' (length=10)
'message' => string 'gjhgjghj' (length=8)
'submit' => string '' (length=0)
重点是如何在表单中显示它们.精确地根据该数组中包含的值选择一些图像.
The point is how to display them in the form. Precisely how to select some images based on the values contained in that array.
由于@Samuraisoulification，这是了解所选内容选项的方法:
This is how to understand which options of the select are selected, thanks to @Samuraisoulification:
<?php
if (isset(Input::old()['rooms']))
{
for($i = 0 , $input = Input::old()['rooms'] , $c = count($input) ; $i < $c ; $i++)
{
if($input[$i] == "Single room")
{
echo "Single room selected";
}
if($input[$i] == "Double room")
{
echo "Double room selected";
}
}
}
?>
推荐答案
这是一个非常精致的解决方案，但如果我正确的话应该可以使用.在选项标签中添加:
This is a very inelegant solution, but should work if I'm correct. In the option tags add:
<?php
for($i = 0 , $input = Input::old()['rooms'] , $c = count($input) ; $i < $c ; $i++){
if($input[$i] == "<select option's name>"){
echo "selected";
}
}
?>
请注意，$ input和$ c不在比较部分，因此它们只会被评估一次，从而为您以后可能拥有的所有选项节省了少量时间(例如页面加载时间).这是一个不太好的解决方案，但是由于您允许多个值，因此我认为这是唯一的方法.旋转一下，让我知道是否有问题！另外，请务必将此代码放在每个开始标签中！
Note that the $input and $c are not in the comparison part so they will only be evaluated once, saving you a small amount of time(like page load time) on all the options you may have later. This is an inelegant solution, but since you allow multiple values, I think this is the only way to do it. Give a whirl and let me know if it has issues! Also be sure to put this code in each opening tag!
我还要说，将所有内容压缩到一条线上看起来也会更好.
Also I would say condensing this all to one line would look better too.
最后，我认为由于选项与输入不同，因此value=="{{Input::old}}"不起作用，因为要选择它，必须说要选择它.另外，请务必评论此hack，以备将来参考.
Lastly, I think because options are different than inputs, the value=="{{Input::old}}" doesn't work, becasue in order for it to be selected you have to say selected on it. Also be sure to comment this hack for future reference.
