带有$ _POST的表单正在向数据库

Question

我已经创建了一个表单来更新前端的几个字段，但是我收到了电子邮件和个人资料图片字段的问题。当我更新这些字段时，一切正常，但是当我再次更新表单时，值只会在表单和数据库中消失。

这是只有两个字段和PHP使用的代码（下面是完整代码）：

<?php

/* Get user info. */
global $current_user, $wp_roles;
get_currentuserinfo();

/* Load the registration file. */
require_once( ABSPATH . WPINC . '/registration.php' );
$error = array();

/* If profile was saved, update profile. */
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'update-user' ) {

    if ( !empty( $_POST['user-email'] ) ){
        if (!is_email(esc_attr( $_POST['user-email'] )))
            $error[] = __('El email que has introducido no es valido, por favor introduce un correo valido.', 'buscopreparador');
        elseif(email_exists(esc_attr( $_POST['user-email'] )) != $current_user->id )
            $error[] = __('Este email ya esta en uso por otro preparador. intenta utilizando otro.', 'buscopreparador');
        else{
            wp_update_user( array ('ID' => $current_user->ID, 'user_email' => esc_attr( $_POST['email'] )));
        }
    }


    /* Update ACF Fields */
    $user_id_acf = 'user_'.$current_user->ID;

    if( !empty( $_FILES['imagen-perfil'] ) ) {

        /* Function to pass the image to the media and database */
        $att = my_update_attachment('imagen-perfil', $user_id_acf);
        update_field('field_56ea616d98e27', $att['attach_id'], $user_id_acf);
    }


    /* Redirect so the page will show updated info.*/
    /*I am not Author of this Code- i dont know why but it worked for me after changing below line to if ( count($error) == 0 ){ */
    if ( count($error) == 0 ) {
        do_action('personal_options_update', $current_user->ID);
        wp_redirect( get_permalink().'?updated=true' ); exit;
    }       
}

get_header(); ?>


<form method="post" id="adduser" action="<?php the_permalink(); ?>" enctype="multipart/form-data">
    <div class="row">


        <!-- Email -->
        <div class="form-group col-md-6">
            <label for="user-email"><?php _e('Email', 'buscopreparador'); ?></label>
            <input type="email" class="form-control" name="user-email" id="user-email" placeholder="danielmartinez@gmail.com" value="<?php the_author_meta( 'user_email', $current_user->ID ); ?>">
        </div>

        <!-- Imagen de Perfil -->
        <div class="form-group col-md-6">
            <label for="imagen-perfil">Imagen de Perfil</label>
            <input type="file" name="imagen-perfil" id="imagen-perfil">
            <p class="help-block">Selecciona tu imagen de perfil, esta debe tener entre 200x200 y 400x400 pixeles.</p>
        </div>


    </div>

    <p class="form-submit">
        <?php echo $referer; ?>
        <input name="updateuser" type="submit" id="updateuser" class="btn btn-primary btn-large" value="<?php _e('Actualizar', 'buscopreparador'); ?>">
        <?php wp_nonce_field( 'update-user_'. $current_user->ID ) ?>
        <input name="action" type="hidden" id="action" value="update-user" />
    </p><!-- .form-submit -->

</form><!-- #adduser -->

这是我更新数据库字段的代码：

<?php
/**
 * Template Name: User Profile
 *
 * Allow users to update their profiles from Frontend.
 */

/* Get user info. */
global $current_user, $wp_roles;
get_currentuserinfo();

/* Load the registration file. */
require_once( ABSPATH . WPINC . '/registration.php' );
$error = array();

/* If profile was saved, update profile. */
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'update-user' ) {

    /* Update user password. */
    if ( !empty($_POST['user-password1'] ) && !empty( $_POST['user-password2'] ) ) {
        if ( $_POST['user-password1'] == $_POST['user-password2'] )
            wp_update_user( array( 'ID' => $current_user->ID, 'user_pass' => esc_attr( $_POST['user-password1'] ) ) );
        else
            $error[] = __('Las contraseñas que has introducido no concuerdan.  No se ha actualizado su contraseña.', 'buscopreparador');
    }

    /* Update user website. */
    if ( !empty( $_POST['user-web'] ) )
       wp_update_user( array ('ID' => $current_user->ID, 'user_url' => esc_attr( $_POST['user-web'] )));

    if ( !empty( $_POST['user-email'] ) ){
        if (!is_email(esc_attr( $_POST['user-email'] )))
            $error[] = __('The Email you entered is not valid.  please try again.', 'buscopreparador');
        elseif(email_exists(esc_attr( $_POST['user-email'] )) != $current_user->id )
            $error[] = __('Este email ya esta en uso por otro preparador. intenta utilizando otro.', 'buscopreparador');
        else{
            wp_update_user( array ('ID' => $current_user->ID, 'user_email' => esc_attr( $_POST['email'] )));
        }
    }


    if ( !empty( $_POST['first-name'] ) )
        update_user_meta( $current_user->ID, 'first_name', esc_attr( $_POST['first-name'] ) );
    if ( !empty( $_POST['last-name'] ) )
        update_user_meta($current_user->ID, 'last_name', esc_attr( $_POST['last-name'] ) );
    if ( !empty( $_POST['nickname'] ) )
        update_user_meta($current_user->ID, 'nickname' , esc_attr( $_POST['nickname'] ));

    /* Update ACF Fields */
    $user_id_acf = 'user_'.$current_user->ID;

    if( !empty( $_POST['titulacion-preparador'] ) )
        update_field( 'field_56e6c502df6af', esc_attr( $_POST['titulacion-preparador'] ), $user_id_acf );

    if( !empty( $_POST['descripcion-breve'] ) )
        update_field( 'field_56e6c622df6b2', esc_textarea( $_POST['descripcion-breve'] ), $user_id_acf );

    if( !empty( $_POST['materiales-disponibles'] ) )
        update_field( 'field_56e939f3d2671', esc_textarea( $_POST['materiales-disponibles'] ), $user_id_acf );

    if( !empty( $_FILES['imagen-perfil'] ) ) {
        $att = my_update_attachment('imagen-perfil', $user_id_acf);
        update_field('field_56ea616d98e27', $att['attach_id'], $user_id_acf);
    }


    /* Redirect so the page will show updated info.*/
    /*I am not Author of this Code- i dont know why but it worked for me after changing below line to if ( count($error) == 0 ){ */
    if ( count($error) == 0 ) {

        do_action('personal_options_update', $current_user->ID);
        wp_redirect( get_permalink().'?updated=true' ); exit;
    }       
}

这是表格代码：

<form method="post" id="adduser" action="<?php the_permalink(); ?>" enctype="multipart/form-data">

    <p class="form-submit">

    </p><!-- .form-submit -->

</form><!-- #adduser -->

Answer 1

为避免发送空图像我使用：

if( !empty( $_FILES['imagen-perfil']['size'] > 0 ) ) {

[＆＃39;尺寸＆＃39;]＆gt; 0 似乎有用，但是，我不知道为什么。无法解决电子邮件问题。
