Php $\u文件数组为空

php file

Php $\u文件数组为空,php,file,Php,File,这是我第一次尝试上载文件，由于某种原因，$\u FILES数组为空。我已经检查了一次又一次我的HTML，它看起来不错。当我尝试在eclipse中调试下面的代码时，检查$\u Files数组时，它是空的。我已经检查了它的php_ini文件： <form action="<?php echo $_SERVER['PHP_SELF']."?requestId=".$requestId?>" enctype="multipart/form-data" method="post" id

在不查看意大利面代码的情况下，首先检查您的$\u帖子是否也是空的

        <input type='hidden' id='requestId' name='requestId' value="<?php echo $requestId;?>"/>
        <input type='hidden' id='listScreen' name='listScreen' value="<?php echo $listScreen;?>"?>  
        <?php 
        if ($CIREM['MAX_IMG_NUM']>0){
            echo "<input type='hidden' name='MAX_FILE_SIZE' value='".$CIREM['MAX_IMG_SIZE']."' />";
            echo "<br/> <strong>Max File size Allowed: </strong>".($CIREM['MAX_IMG_SIZE']/1000000)." Mb <br/><strong>File Formats Allowed: </strong>".$CIREM['IMG_TYPES']."<br/><hr/>";?>

        <?php   for ($i=1;$i<=$CIREM['MAX_IMG_NUM'];$i++){?>


                <div class="controls input">
                    <input class="input-file" type="file" name="upload_file[]" id="upload_file[]"/><br/>
                </div>

            <?php }?>

        <?php }
        else{
            echo "<p class='alert alert-info'>Attachment uploading is not allowed</p>";
        }
        ?>



如果是，请确保post_max_大小大于upload_max_filesize。这两种设置必须是一致的。
首先，很抱歉回复太晚，但由于有时人们会偶然发现有关stackoverflow的旧主题，所以我决定按照自己的方式编写


<form  action="<?php echo $_SERVER['PHP_SELF']."?requestId=".$requestId?>" enctype="multipart/form-data" method="post" id="addattachment" name="addattachment" class="form-vertical" autocomplete="off">
        <input type='hidden' id='requestId' name='requestId' value="<?php echo $requestId;?>"/>
        <input type='hidden' id='listScreen' name='listScreen' value="<?php echo $listScreen;?>"?>  
        <?php 
        if ($CIREM['MAX_IMG_NUM']>0){
            echo "<input type='hidden' name='MAX_FILE_SIZE' value='".$CIREM['MAX_IMG_SIZE']."' />";
            echo "<br/> <strong>Max File size Allowed: </strong>".($CIREM['MAX_IMG_SIZE']/1000000)." Mb <br/><strong>File Formats Allowed: </strong>".$CIREM['IMG_TYPES']."<br/><hr/>";?>

        <?php   for ($i=1;$i<=$CIREM['MAX_IMG_NUM'];$i++){?>


                <div class="controls input">
                    <input class="input-file" type="file" name="upload_file[]" id="upload_file[]"/><br/>
                </div>

            <?php }?>

        <?php }
        else{
            echo "<p class='alert alert-info'>Attachment uploading is not allowed</p>";
        }
        ?>


因此，要通过ajax发送文件，必须使用FormData


<form  action="<?php echo $_SERVER['PHP_SELF']."?requestId=".$requestId?>" enctype="multipart/form-data" method="post" id="addattachment" name="addattachment" class="form-vertical" autocomplete="off">
        <input type='hidden' id='requestId' name='requestId' value="<?php echo $requestId;?>"/>
        <input type='hidden' id='listScreen' name='listScreen' value="<?php echo $listScreen;?>"?>  
        <?php 
        if ($CIREM['MAX_IMG_NUM']>0){
            echo "<input type='hidden' name='MAX_FILE_SIZE' value='".$CIREM['MAX_IMG_SIZE']."' />";
            echo "<br/> <strong>Max File size Allowed: </strong>".($CIREM['MAX_IMG_SIZE']/1000000)." Mb <br/><strong>File Formats Allowed: </strong>".$CIREM['IMG_TYPES']."<br/><hr/>";?>

        <?php   for ($i=1;$i<=$CIREM['MAX_IMG_NUM'];$i++){?>


                <div class="controls input">
                    <input class="input-file" type="file" name="upload_file[]" id="upload_file[]"/><br/>
                </div>

            <?php }?>

        <?php }
        else{
            echo "<p class='alert alert-info'>Attachment uploading is not allowed</p>";
        }
        ?>

就是这样，使用formData它可以很好地发送文件。
您的PHP只输出与HTML类似的表单。真正有问题的代码在哪里？我认为删除不必要的东西以使其可压缩会对您（和其他人）有利。例如，
与此无关。它所做的只是使问题复杂化。另外，看起来您只是在向我们展示两个表单，您的代码中甚至没有单词
$\u FILES
。。。同样，在你的帖子正文中，你引用了不正确的
$\u文件
。实际处理上传文件的代码在哪里？我认为
id=“upload\u file[]”
不是有效的HTML，但我怀疑这会导致你的问题。你不需要指定
method=“post”
？我只是这样做了，但它不起作用。如果我查看php日志会有帮助吗？
