如何从HTML表中获取数据并将其放在PHP文本字段中

您可能希望像这样通过ajax完成所有操作:

table html page

<table class="table table-striped table-bordered" id="example">
    <thead>
    <?php
        foreach ($fields as $field_name => $field_display){
            echo "<th>$field_display</th>";
        }
    ?>
    </thead>
    <tbody>
    <?php
        foreach ($users as $row){
            echo "<tr>";
            foreach($fields as $field_name => $field_display){
                if($field_name == 'username'){
                    echo "<td><a href='#' onclick='"edituserdata('".$row->username."')'">".$row->$field_name."</a></td>";
                } else {
                    echo "<td>".$row->$field_name."</td>";
                }
            }
            echo "</tr>";
        }
    ?>
    </tbody>
</table>   
<!-- Modal -->
<div id="myModal1" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Update you're data</h3>
    </div>
    <div class="modal-body">
        <!-- NOTE THE EMPTY MODAL -->
    </div>
    <div class="modal-footer">
        <div class="container-fluid">
            <div class="row-fluid">
                <div class="span5" id="message_add_user_id">
                </div>
                <div class="span7">
                    <button id="add_user_submit" type="button" class="btn btn-success">Update <i class="icon-white icon-check"></i> </button>
                    <button class="btn" onClick="document.location.reload(true)" data-dismiss="modal" >Close</button>
                </div>          
            </div>
        </div>
    </div>
</div>

<?php echo form_open('main/update'); ?>
<?php 
    // TODO get username from $_GET['username'] and then retrieve all user information from db
    // TODO echo user data into form fields
    $name = array(
            'name' => 'name',
            'id' => 'name',
            'value' => set_value('name')
    );
    ?>
    <div class="control-group">
        <label class = "control-label" for="name">Name:</label>
        <div>
            <input type="text" name="name" placeholder="Name" id="name" value="">
            <?php echo form_error('name', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">
        <label class = "control-label" for="name">Username:</label>
        <div>
            <input type="text" name="username" placeholder="Username" id="username" value="">
            <?php echo form_error('username', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">
        <label class = "control-label" for="name">Password: </label>
        <div>
            <input type="password" name="password" placeholder="Password" id="password" value="">
            <?php echo form_error('password', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">
        <label class = "control-label" for="name">Retype password: </label>
        <div>
            <input type="password" name="password1" placeholder="Retype password" id="password1" value="">
            <?php echo form_error('password1', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">

        <div>
            <input type="email" name="email" placeholder="Email" id="email" value="">
            <?php echo form_error('email', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">
        <label class = "control-label" for="name">Phone number: </label>
        <div>
            <input type="tel" name="tel" placeholder="Phone number" id="phone_number" value="">
            <?php echo form_error('tel', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
    <div class="control-group">
        <label class = "control-label" for="name">Description: </label>
        <div>
            <input type="text" placeholder="Description" name="descr" id="description" value="">
            <?php echo form_error('descr', '<span class="alert-error help-inline">', '</span>')?>
        </div>
    </div>
<?php echo form_close();?>

Javascript在table page

<script>
    function edituserdata(username) {
        $.get('url-to-ajax-page', {username: username}, function(resp) {
            $('#myModal1 .modal-body').html(resp);
            $('#myModal1').modal('show');
        });
    }
</script>

我们在这里做的是创建一个包含用户名的表。当您单击用户名时，它会对页面进行ajax调用，该页面使用用户数据填充表单数据，并在模态中显示。

这应该可以让你开始了。至于提交表单，我就没时间写了但你要做的是，当他们点击提交按钮时，有另一个ajax查询它会将数据发送到相同的ajax url。当数据返回时，如果发布的数据中有错误，则用ajax响应替换模型体的内容，否则关闭窗口。
