Question

我从目录cv::vector<cv::Vec3f> circles获取的图片很少。我必须从所有图像中删除一个图像，我想显示确认警报，如是或否。如果是，则获取图像的值并将其传递到下一页。 $files = glob("images/image/$til/$subtil/*.*");这是我必须获取的变量并在下一页中发布

$detatil="delete.php?image=$image&til=$til&subtil=$subtil";

您可以通过在函数中传递值来实现目标：

<?php
$subtil=$_GET['subtil1'];
$til=$_GET['til1'];
 $files = glob("images/image/$til/$subtil/*.*");
            $count=count($files);
            for ($i=0; $i<$count; $i++) 
            { 

              echo "<div class='pitem entry item-w1 item-h1'  style='padding: 15px;'>";

              $image = $files[$i];
              echo "<img src='".$image."' class='img-responsive' style='padding:20px;border:1px solid black;'>"."";
              echo "<br>";
              $detatil="delete.php?image=$image&til=$til&subtil=$subtil";
              echo"<span style='float: center;padding-top: 10px;'><button type='submit' onclick=myFunction('$detail') name='submit' value='Send' class='btn btn-primary'>Delete</button></span>";

              //echo $detatil;
              echo "</div>";
?>

            <script>

            function myFunction(url) {
                  var r=confirm("Do you want to leave page!");
                if (r)
                {
                    //write redirection code
                    window.location = url;
                }
                else
               {
                    //do nothing
                }    //document.getElementById("demo").innerHTML = txt;
            }
            </script>  

            <?php
                        }//for loop end 
            ?>
