php - 无法使用多个文件输入字段。曾德

Question

似乎找不到我的问题，但我想做的是为项目组提供一个编辑表单，它可以有 4 张图像。 当我尝试上传所有四张图片时，它有效，当我只上传 1 张时，它没有。

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>

代码:编辑 Action

public function groupEditAction()
{
    $id = $this->getRequest()->getParam('id');
    $projectGroup = new ProjectGroup($id);

    $name = Array();
    $langs = LangFuncs::getAllLangs();
    foreach($langs as $lang) {
        $langId = $lang->getId();

        $name[$langId] = $this->getRequest()->getParam("name-$langId");
    }

    $projectGroup->edit(null, $name);

    $upload = new Zend_File_Transfer_Adapter_Http();
    $upload->setDestination(URLgenerator::getTempFolder());
    $upload->receive();
    $info = $upload->getFileInfo();
    var_dump($info);
    return;
    foreach($langs as $lang) {
        $langId = $lang->getId();
        try { 
            if($info["imageOff-$langId"]['tmp_name'] != '') {
                $projectGroup->uploadImageOff($lang, $info["imageOff-$langId"]['tmp_name']);
                unlink($info["imageOff-$langId"]['tmp_name']);
            }
            if($info["imageOn-$langId"]['tmp_name'] != '') {
                $projectGroup->uploadImageOn($lang, $info["imageOn-$langId"]['tmp_name']);
                unlink($info["imageOn-$langId"]['tmp_name']);
            }
        } 
        catch (Zend_File_Transfer_Exception $e) { 
            $this->_helper->redirector('image-upload', 'error', 'admin', array());
        }
    } 

    $this->_helper->redirector('index', 'project', 'admin', array());
}

当我执行 var_dump 时我得到了什么:

附言。 也许我可以通过使用这个临时名称并使用它来让它工作，但在正常情况下，我知道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。当我获得 .tmp 时，我什么也没做，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，请评论。

您可能需要将 ignoreNoFile 设置为 true。看看这篇文章是否有帮助:Zend_File_Transfer w/multiple files does not upload equally
