标签： javascript php image

工作模具文本项目我已创建代码将输入文本转换为图像它工作正常，但我有多个文本框（例如）文本框1，文本框2，文本框3.问题是如果我键入文本框1其将文本转换为图像，之后如果我在文本框2或文本框3中键入文本，则在此处转换新图像我只想在新行中使用文本框1中的第一个图像转换文本创建该文本。

贝娄示例快照。您可以看到第一个文本框包围第1行和第二个文本框在一个图像上的第二行或新行上创建图像。

different line

Bellow是我的代码index.php 

<?php ?>

 <html>
 <body>

 <img class="stencil-main" id="stencil-main" />
<span class="line" style="margin-left: 578px;">Enter Text-</span><input type="text" name="stencil-text" style="margin-left: 15px;"
       onkeyup="document.getElementById('stencil-main').src='some.php?img='+this.value" />

        <br> 
        <img class="stencil-mains" id="stencil-mains" />    
        <span class="line" style="margin-left: 578px;">Enter Text-</span><input type="text" name="stencil-text" style="margin-left: 15px;"
       onkeyup="document.getElementById('stencil-mains').src='some.php?img='+this.value" />


       </body>
       </html>

2）Bellow是用于将文本转换为图像的PHP代码some.php 

<?php
  header("Content-type: image/png");
$cid=$_GET['img'];

$imagewidth = 500;
$imageheight = 100;
$fontsize = "20";
$fontangle = "0";
$font = "ByzantineEmpire.ttf";
$text = $cid ;
$text2="sanjay";
$backgroundcolor = "FFFFFF";
$textcolor = "#000000";

### Create image
$im = imagecreate( $imagewidth, $imageheight );

### Declare image's background color
$bgcolor = imagecolorallocate($im, $bgred,$bggreen,$bgblue);

### Declare image's text color
$fontcolor = imagecolorallocate($im, $textred,$textgreen,$textblue);

### Get exact dimensions of text string
$box = @imageTTFBbox($fontsize,$fontangle,$font,$text);

### Get width of text from dimensions
$textwidth = abs($box[4] - $box[0]);

### Get height of text from dimensions
$textheight = abs($box[5] - $box[1]);

### Get x-coordinate of centered text horizontally using length of the image and length of the text
$xcord = ($imagewidth/2)-($textwidth/2)-2;

### Get y-coordinate of centered text vertically using height of the image and height of the text
$ycord = ($imageheight/2)+($textheight/2);

### Declare completed image with colors, font, text, and text location
imagettftext ( $im, $fontsize, $fontangle, $xcord, $ycord, $fontcolor, $font, $text );

### Display completed image as PNG

### Close the image

您需要获取文本字段的值并将它们全部发送到some.php，现在您将单独发送它们。 some.php也需要同时获取它们并使用它们生成单个图像。以下是使用jQuery加载函数的方法：

index.php 

<html>
<head>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function(){

            $('input[name="stencil-text"]').keyup(function(){

                var img_text = $('input[name="stencil-text"]').map(function(){
                    return $(this).val();
                }).get();

                var img = $("<img />").attr('src', 'some.php?img=' + img_text).load(function() {
                    if (!this.complete || typeof this.naturalWidth == "undefined" || this.naturalWidth == 0) {
                        alert('broken image!');
                    } else {
                        $("#stencil-main").html(img);
                    }
                });

            });

        });
    </script>
</head>
<body>
    <div id="stencil-main"></div>
    <span class="line" style="margin-left: 578px;">Enter Text-</span>
    <input type="text" name="stencil-text" style="margin-left: 15px;">

    <br>

    <span class="line" style="margin-left: 578px;">Enter Text-</span>
    <input type="text" name="stencil-text" style="margin-left: 15px;">
</body>
</html>

这里jQuery获取名称为“stencil-text”的输入字段的所有值，您可以添加所需数量的输入字段，它将以相同的方式工作。您唯一需要做的就是更改$imageheight，否则图像将被裁剪。

some.php 

<?php
header("Content-type: image/png");
$cid = str_replace(',', "\n", $_GET['img']);
####################### BEGIN USER EDITS #######################
$imagewidth = 500;
$imageheight = 120;
$fontsize = "20";
$fontangle = "0";
$font = "ByzantineEmpire.ttf";
$text = $cid ;
$text2="sanjay";
$backgroundcolor = "FFFFFF";
$textcolor = "#000000";
