php选择fetch while循环进入引导模式
有一些数据库信息,我正试图进入一些模态 问题似乎是模态只从最后一个while循环中获取变量。页面上的所有php都先运行吗?即使它没有被呼叫 因此,我知道使用get_results、fetch_array和fetch_row可能有更简单的方法来实现这一点,但在PHP5.5中,这些方法似乎不适用于我 另外,我在某个地方读到了使用AJAX的文章。我以前从未使用过ajax,这是我应该研究的问题吗php选择fetch while循环进入引导模式,php,twitter-bootstrap,modal-dialog,Php,Twitter Bootstrap,Modal Dialog,有一些数据库信息,我正试图进入一些模态 问题似乎是模态只从最后一个while循环中获取变量。页面上的所有php都先运行吗?即使它没有被呼叫 因此,我知道使用get_results、fetch_array和fetch_row可能有更简单的方法来实现这一点,但在PHP5.5中,这些方法似乎不适用于我 另外,我在某个地方读到了使用AJAX的文章。我以前从未使用过ajax,这是我应该研究的问题吗 <div class="col-md-4"> <?php error_re

变量在这里,工作正常。问题是,我使用相同的bind_结果变量运行了几次相同的php脚本。我真的不想改变每个模式的变量
模态:
一种方法是在$stmt->fetch{}同时分配模态触发器按钮和模态本身的唯一id时,将模态放入其中 注意模态触发器按钮中的数据target=modalPort和模态HTML中的id=modalPort
<?php while ($stmt->fetch()) { ?>
<button data-toggle="modal" data-target="#modalPort<?php echo $id;?>" class="btn btn-default">Modal</button>
<div class="modal fade" id="modalPort<?php echo $id;?>" tabindex="-1" role="dialog" aria-labelledby="portfolioModallabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="portfolioModallabel"><?php echo $title; ?></h4>
</div>
<div class="modal-body text-center">
<img class="img-responsive center-block" src="<?php echo $thumbpath; ?>" sizes="100vw" srcset="<?php echo $smallpath; ?> 500w, <?php echo $mediumpath; ?> 1000w, <?php echo $largepath; ?> 1500w" alt="Portfolio Site">
<p class="line-height-small"><?php echo $descript; ?></p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<?php } ?>
Modal listener获取数据属性值,然后在Ajax方法中使用,以获取要在Modal中显示的相应行数据
$(document).ready(function(){
$('#modalPort').on('show.bs.modal', function (e) {
var dataid = $(e.relatedTarget).data('id');
var dataString = 'dataid=' + dataid;
$.ajax({
type: "POST",
url: "get_data.php",
data: dataString,
cache: false,
success: function(data){
$("#content").html(data);
}
});
});
});
get_data.php将是
<?php
//Include database connection
if($_POST['dataid']) {
//run query against `dataid`
?>
<div class="modal-header">
<h4 class="modal-title" id="portfolioModallabel"><?php echo $title; ?></h4>
</div>
<div class="modal-body text-center">
<img class="img-responsive center-block" src="<?php echo $thumbpath; ?>" sizes="100vw" srcset="<?php echo $smallpath; ?> 500w, <?php echo $mediumpath; ?> 1000w, <?php echo $largepath; ?> 1500w" alt="Portfolio Site">
<p class="line-height-small"><?php echo $descript; ?></p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
<?php } ?>
模式HTML将在循环之外
<div class="modal fade" id="modalPort" tabindex="-1" role="dialog" aria-labelledby="portfolioModallabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div id="content"></div> //display data output via ajax
</div>
</div>
</div>
非常感谢你的帮助,Shehary!
