如何將多條記錄添加到我的數據庫中

Question

一直在使用表單。我想將表單中的信息添加到數據庫中，以便我可以在網站上的其他日曆中顯示它。

我在網上發現了一些其他代碼，但只適用於1值。由於某種原因只有一次。 現在有這個（在WordPress工作BTW）

function elh_insert_into_db() { 

global $wpdb; 
// creates my_table in database if not exists 
$table = $wpdb->prefix . "table_form"; 
$charset_collate = $wpdb->get_charset_collate(); 
$sql = "CREATE TABLE IF NOT EXISTS $table (
    `id` mediumint(9) NOT NULL AUTO_INCREMENT, 
    `name` text NOT NULL, 
    `email` text NOT NULL, 
    `date` text NOT NULL, 
    `starttijd` text NOT NULL, 
    `eindtijd` text NOT NULL, 
    `opmerkingen` text NOT NULL, 
UNIQUE (`id`) 
) $charset_collate;"; 
require_once(ABSPATH . 'wp-admin/includes/upgrade.php'); 
dbDelta($sql); 
// starts output buffering 
ob_start(); 
?> 
<form action="#v_form" method="post" id="v_form"> 
    <label for="visitor_name"><h3>Naam:</h3></label> 
     <input type="text" name="visitor_name" id="visitor_name" /> 

<label for="visitor_email"><h3>E-mail:</h3></label> 
    <input type="email" name="visitor_email" id="visitor_email" /> 

<label for="visitor_date"><h3>Datum:</h3></label> 
    <input type="date" name="visitor_date" id="visitor_date" /> 

<label for="visitor_start_time"><h3>Starttijd:</h3></label> 
    <input type="time" name="visitor_start_time" id="visitor_start_time" /> 

<label for="visitor_end_time"><h3>Eindtijd:</h3></label> 
    <input type="time" name="visitor_end_time" id="visitor_end_time" /> 

    <label for="visitor_text"><h3>Opmerkingen:</h3></label> 
     <input type="text" name="visitor_text" id="visitor_text" /> 

    <input type="submit" name="submit_form" value="Aanvragen" /> 
</form> 
<?php 
$html = ob_get_clean(); 
// does the inserting, in case the form is filled and submitted 
if (isset($_POST["submit_form"]) && $_POST["visitor_name"] != "") { 
$table = $wpdb->prefix."table_form"; 
$name = strip_tags($_POST["visitor_name"], ""); 
$wpdb->insert( 
    $table, 
    array( 
     'name' => $name 
    ) 
); 


    $html = "<p>check this is inserted in the database <strong>$name, $email, $date , $starttijd, 
$eindtijd, $opmerkingen</strong> what a succes!</p>"; 
} 
// if the form is submitted but the name is empty 
if (isset($_POST["submit_form"]) && $_POST["visitor_name"] == "") 
    $html .= "<p>You need to fill the required fields.</p>"; 
// outputs everything 
return $html; 

} 
// adds a shortcode you can use: [insert-into-db] 
add_shortcode('elh-db-insert', 'elh_insert_into_db'); 

Answer 1

你只過程/插入名稱（形成你的代碼）：

$name = strip_tags($_POST["visitor_name"], "");  
$wpdb->insert( 
    $table, 
    array( 
     'name' => $name 
    ) 
) 

修改的代碼，這部分增加其他信息。需要處理$ _POST中的每個項目。

很好的起點上形式（和許多其他的事情！）：https://www.w3schools.com/php/php_forms.asp
