PHP动作表单嵌入HTML

Question

我的表单操作页面是PHP，但是我想显示可点击的链接，我认为PHP不支持此链接。 我已将此PHP代码嵌入HTML标记中，但它会在页面中显示这些标记。

码：

<?php
header('content-type: application/json; charset=utf-8');
header("access-control-allow-origin: *");

include 'connect.php';

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);


// Allow certain file formats
if($imageFileType != "sql") {
    echo "Sorry, only SQL files are allowed.\n";
    $uploadOk = 0;
}

// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.\n";
        $sqlfile = fopen($target_file, "r") or die("Unable to open file!");
        $contents = file($target_file);
        foreach($contents as $line) {
            $result = mysql_query($line) or die('Query failed: ' . mysql_error());
            $file_name= str_replace("'", "", basename($target_file,".sql"));


        }


        echo "The new data was inserted in database.\n";
        echo "View your data in http://localhost/public_html/PAD/index.php?user=$file_name";
        fclose($sqlfile);

    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}


?>

问题在这里：

echo "View your data in http://localhost/public_html/PAD/index.php?user=$file_name";

如何使该链接可点击？

谢谢！

Answer 1

检查标题：

你有

header('content-type: application/json; charset=utf-8');

application/json标头不能返回HTML 。 他们将返回JSON字符串。 在JSON中，标记将按原样返回，不会被渲染。

你需要：

header('content-type: text/html; charset=utf-8');

然后，当您希望显示链接时，将该链接括在A标记中：

echo 'View your data in <a href="http://localhost/public_html/PAD/index.php?user='.$file_name.'">http://localhost/public_html/PAD/index.php?user='.$file_name.'</a>';

试试吧

<?php

header（'content-type：text / html; charset = utf-8'）; header（“ access-control-allow-origin：*”）;

include 'connect.php';

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);


// Allow certain file formats
if($imageFileType != "sql") {
    echo "Sorry, only SQL files are allowed.\n";
    $uploadOk = 0;
}

// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.\n";
        $sqlfile = fopen($target_file, "r") or die("Unable to open file!");
        $contents = file($target_file);
        foreach($contents as $line) {
            $result = mysql_query($line) or die('Query failed: ' . mysql_error());
            $file_name= str_replace("'", "", basename($target_file,".sql"));


        }


        echo "The new data was inserted in database.\n";
        echo '<a href="http://localhost/public_html/PAD/index.php?user=$file_name">View your data in </a>';
        fclose($sqlfile);

    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}


?>

您的问题似乎已经回答了自己。 您所要做的就是将链接包装在Anchor Tag中，就像这样

<?php
    header('content-type: application/json; charset=utf-8');
    header("access-control-allow-origin: *");

    include 'connect.php';

    $target_dir    = "uploads/";
    $target_file   = $target_dir . basename($_FILES["fileToUpload"]["name"]);
    $uploadOk      = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);


    // Allow certain file formats
    if($imageFileType != "sql") {
        echo "Sorry, only SQL files are allowed.\n";
        $uploadOk = 0;
    }

    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Your file was not uploaded.";
       // if everything is ok, try to upload file
    } else {
   if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.\n";
        $sqlfile = fopen($target_file, "r") or die("Unable to open file!");
        $contents = file($target_file);
    foreach($contents as $line) {
        $result = mysql_query($line) or die('Query failed: ' . mysql_error());
        $file_name= str_replace("'", "", basename($target_file,".sql"));
    }


    echo "The new data was inserted in database.\n";
    //THIS IS THE ONLY PLACE YOU NEED TO ADDRESS: WRAP URL IN <A> TAGS:
    echo "<a href='http://localhost/public_html/PAD/index.php?user={$file_name}' class='view-data-link'>View your data</a>";
    fclose($sqlfile);

} else {
    echo "Sorry, there was an error uploading your file.";
}

}
