Php 不能使用多个文件输入字段。泽德

似乎找不到我的问题，但我正试图做的是有一个项目组的编辑表单，它可以有4个图像。 当我试着上传所有四张图片时，效果很好，而当我只上传一张时，效果就不好了

代码：HTML表单

<?php
    $langs = $this->langs;
    $projectGroup = $this->projectGroup;
?>
<div id="box">
    <h3>Edit Project Group</h3>
    <form id = "form" name = "form" action="<?php echo URLgenerator::getURL('project', 'group-edit', array('id' => $projectGroup->getId()), 'admin'); ?>" method="post" enctype='multipart/form-data'>
        <?php 
            foreach($langs as $lang):
                $langId = $lang->getId();
                $displayName = $lang->getDisplayName();
        ?>
            <fieldset id="In<?php echo $displayName; ?>">
                <legend id ="<?php echo $langId?>">
                    <?php echo $displayName; ?>: 
                </legend> 
                <label for="name-<?php echo $langId; ?>">Name: </label> 
                <input type="text" id="name-<?php echo $langId; ?>" name="name-<?php echo $langId; ?>" style="width: 500px;" value="<?php echo $projectGroup->getName($lang); ?>" />
                <br />
                <label for="imageOff-<?php echo $langId; ?>">Image Off: </label> 
                <input type="file" id="imageOff-<?php echo $langId; ?>" name="imageOff-<?php echo $langId; ?>" />
                <img src="<?php echo $projectGroup->getImageOffURL($lang); ?>" />
                <br />
                <label for="imageOn-<?php echo $langId; ?>">Image On: </label> 
                <input type="file" id="imageOn-<?php echo $langId; ?>" name="imageOn-<?php echo $langId; ?>" />
                <img src="<?php echo $projectGroup->getImageOnURL($lang); ?>" />
            </fieldset>
        <?php 
            endforeach;
        ?>
        <div align="center">
            <input type="submit" value="Edit" id="button1" /> 
            <input type="reset" id="button2" />
        </div>
    </form>
</div>

<script type="text/javascript">
    <?php 
        foreach($langs as $lang):
            $langId = $lang->getId();
    ?>
    $('#<?php echo $langId; ?>').click(function() {
        $('#div-<?php echo $langId; ?>').toggle();
    });
    <?php 
        endforeach;
    ?>
</script>

以及我在进行var_转储时得到的：

附言。 也许我可以通过使用这个临时名称并使用它来实现它，但是在正常情况下，我得到临时名称有一个正常的扩展名，而不是.tmp，所以我使用它作为扩展名。当我得到.tmp时，我什么也不做，因为它不是.jpg、.png或.gif（在我的上传功能中）

如果您也需要上传功能，请发表评论。

您可能需要将ignoreNoFile设置为true。看看这篇文章是否有用：
