Question

我一直在这个问题上困扰了好几天，并且我对这个问题很担心......我不知道我在做什么错，或者我应该寻找帮助。

我有一个搜索页面，允许用户筛选一些类别的结果。

这是视图：

<form method="post" id="search_form" name="search_form"> 
<input type='hidden' id='seeking_gender_id' value='<?php echo $profile->gender_id ?>'/> 

<div id='sidebar_wrapper'> 
    <div id='sidebar'> 
    <div class="slider_header"> 
    Country 
    </div> 
    <div class="slider_content"> 
    <select id="country_dropdown" name="country_dropdown"> 
    <?php 
    if($countries->num_rows() > 0) 
    { 
     foreach($countries->result() as $row) 
     { 
     $selected = ($row->country_id == $profile->country_id ? "selected='yes'" : ""); 
     echo "<option value='" . $row->country_id . "' " . $selected . ">" . $row->country ."</option>"; 
     } 
    } 
    ?> 
    </select> 
    </div> 
    <div class="slider_header"> 
    Region 
    </div> 
    <div class="slider_content"> 
    <select id='region_dropdown' name='region_dropdown'> 
    <option value="0">All regions</option> 
    <?php 
     if($regions->num_rows() > 0) 
     { 
     foreach($regions->result() as $row) 
     { 
     $selected = ($row->region_id == $profile->region_id ? "selected='yes'" : ""); 
     echo "<option value='" . $row->region_id . "' " . $selected . ">" . $row->region ."</option>"; 
     } 
     } 
    ?> 
    </select> 
    </div> 
    <div class="slider_header"> 
    Gender 
    </div> 
    <div class="slider_content"> 
    <?php 
    $male_checked = ($profile->seeking_gender_id == 1 ? "checked='yes'" : ""); 
    $female_checked = ($profile->seeking_gender_id == 2 ? "checked='yes'" : ""); 
    ?> 
    <input id='male_checkbox' type="checkbox" name="genders" <?php echo $male_checked ?> value="1" /> 
    Male 
    <br/> 
    <input id='female_checkbox' type="checkbox" name="genders" <?php echo $female_checked ?> value="2" /> 
    Female 
    </div> 
    <div class="slider_header"> 
    Age 
    </div> 
    <div class="slider_content"> 
    Between 
    <input id="min_age" type="text" maxlength="2" style="width: 35px" value='<?php echo $profile->min_age ?>'/> 
    and 
    <input id="max_age" type="text" maxlength="2" style="width: 35px" value='<?php echo $profile->max_age ?>'/> 
    </div> 
    <input id='profile_search_button' type='button' value='Search'></input> 
    </div> 
    <div id='sidebar_content'> 
    <div id='content_header'> 
    Search 
    <div id='profiles_found' style='float: right'>0</div> 
    </div> 
    <div id='search_results'></div> 
    </div> 
    <div id='sidebar_footer'></div> 
</div> 
</form> 

所以，当点击 “profile_search_button” 的时候，下面的jQuery代码运行：

$("#profile_search_button").click(function() 
{ 
    $('#search_results').hide(); 

    $.post("http://localhost/index.php/search/search_database", 
    function(data) 
    { $('#search_results').html(data); 
    $('#search_results').slideDown('slow'); 
    }); 
}); 

该函数调用下面的PHP函数：

public function search_database() 
{ 
// HOW AM I MEANT TO GET THE VALUES OF THE FORM FILTERS? eg: country_id, region_id etc 

$this->load->library('Jquery_pagination'); 

$config['base_url'] = site_url('search/blahh/'); 
$config['total_rows'] = 100; 
$config['per_page'] = '10'; 
$config['div'] = '#search_results'; 

$this->jquery_pagination->initialize($config); 
echo $this->jquery_pagination->create_links(); 
} 

上面的代码工作...我只是不知道如何读取过滤器的值“search_database”PHP函数。

我已经工作过这个例子，但是这就是我似乎可以找到：

任何人能帮助我们吗？

Answer 1

使用$ .post的'data'部分。

http://api.jquery.com/jQuery.post/

$.ajax({ 
    type: 'POST', 
    url: url, 
    data: { $('#form_field').val() }, 
    etc. 

Answer 2

得到它的工作家伙。只是一些愚蠢的错误。 只好连载的形式数据，而不是发送它作为一个JSON对象

$("#profile_search_button").click(function() 
{ 
    $('#search_results').hide(); 

    $.post("http://localhost/index.php/search/search_database", serialize_form(), 
    function(data) 
    { 
     $('#search_results').html(data); 
     $('#search_results').slideDown('slow'); 
    }); 
}); 

和事实证明，“additional_param”是工作毕竟。
