Question

我似乎无法在我的php文件中过去isset（$ _ FILES ['formFile']），它总是返回false。我正在使用Ext js 4.1 我的目标是将这些图像存储在blob中。

Extjs代码：

  var fi = new Ext.FormPanel({            
        fileUpload: true,
        width: 400,
        frame: false,            
        autoHeight: true,            
        labelWidth: 40,
        border: false,            
        margins: '10 0 0 10',
        defaults: {
            anchor: '95%',
            allowBlank: false,
            msgTarget: 'side',
            border: false
        },
        items: [{
            xtype: 'filefield',                
            emptyText: 'Select an image',
            fieldLabel: 'Image',
            id: 'formFile',
            buttonCfg: {
                text: '',
                iconCls: 'upload-icon'
            },
            border: false
        }],
        buttons: [{
            text: 'Upload',
            handler: function(){
                var form = this.up('form').getForm();                    
                if(form.isValid()){
                    form.submit({
                        url: 'php/picture-upload.php',
                        waitMsg: 'Uploading your image...',
                        success: function(fi, o){                                
                            alert('succes');
                        }
                    });
                }
            }
        }]
    });

PHP：

if (!isset($_FILES['formFile'])) {
echo '<p>Please select a file</p>';
echo '{"success": false}';
} else {
try {
    upload();
    echo '<p>Thank you for submitting</p>';
} catch (Exception $e) {
    echo $e->getMessage();
    echo 'Sorry, could not upload file';
}
}

print_r的输出（$ _ FILES）;

Array
(
[formFile-inputEl] => Array
    (
        [name] => clicla.jpg
        [type] => image/jpeg
        [tmp_name] => /Applications/MAMP/tmp/php/phpnUxgV3
        [error] => 0
        [size] => 6772
    )

Answer 1

isset应根据您的输出检查formFile-inputEl。

if (!isset($_FILES['formFile-inputEl'])) {
}

将图像文件发送到php
