php line graph

Fri, 20 Nov 2009 03:45:14 -0700

I need to make a line graph in php but my problem is that I need to plot many data points on an image of 600px x 400px. Does anyone have any ideas of how to do this? I tried searching around for a solution but haven't found one. The graph would need more than 600 datapoints so I would have to separate each point by less than 1px which I don't think is possible. I have seen graphs online that plot more than 20,000 data points on relatively smaller images. So I know its possible I just don't know how to do it.

Thanks,

Re: JavaScript function call

I'm not sure if size is a keyword in javascript - if it is, that may be part of the problem. I usually create 2D arrays using something like below.

 
var arr = new Array(5), i, j;

for(i=0; i < 5; i++) {
   arr[i] = new Array(2);
}

arr[0][0] = some_val;
arr[0][1] = some_val;
...
arr[4][0] = some_val;
arr[4][1] = some_val;

I don't really follow you. What values are you placing in the array, and is it more than one array? I don't know if it will help you or not.

$n = 1;

echo "<script type='text/javascript'>\n";

while($n <= 5) {

   echo "var arr" . $n . " = new Array(";

   for($i=0; $i < 10; $i++) {
      echo ($i < 9 ? $i . ", " : $i . ");\n");
   }

   $n++;
}

echo "</script>";

Re: dynamcially generate a table

Wed, 18 Nov 2009 23:45:47 -0700

Not entirely sure about the form, but as an example, you can add a table using something like below. You could *probably* add something similar to a form once you have its id, tagname, or index pos.

<script type="text/javascript">

function addTable() {

try {
   var d = document.getElementById("divName");
   var htm = "<table width='50' align='center' border='1'>" +
             "<tbody>" +
             "<th>Dynamic Table</th>" + 
             "<tr>" +
             "   <td width='100%' align='center' valign='top'>" +
             "      <p>test</p>" +
             "   </td>" +
             "</tr>" +
             "</tbody>" +
             "</table>";

   d.innerHTML = htm;
   delete(htm);
   delete(d);
} catch(e) { alert("Error: " + e.message); }
}
</script>

<input type="button" onclick="addTable();">
<div id="divName"></div>

You can integrate reCAPTCHA with php pages. That will do solve the problem.

PHP developed comunity

Mon, 02 Nov 2009 07:21:07 -0700

Hi there,

I have developed a site with PHPFOX script. I have applied all the known techniques in order to increase traffic (new content everyday, article submisions, blogs comments, ect), I have also applied a Script (phpfoxseo) which should make more SEO friendly each page of the site (meta tags, meta description, etc).

But still the site does not get visitors. PHPFOX admit their script "is not very SEO friendly" since it has several years already" however they also shows several websites which may be very susscessfull.

Could you guys have a look into the site in my signature and tell me if there is any obvious mistake on it?

Could you please advice me where to find a good SEO company which analize the site and give directions?

Re: Stop Spam

Sat, 31 Oct 2009 15:06:37 -0700

It does have something which is similar with Captch Code.
I am not sure that are they same?

<td class="altbg1" width="21%"><span class="bold">CheckCode</span></td>
<td class="altbg2"> <div id="seccodeimage"></div><div class="input"><input type="text" name="seccodeverify" size="4" maxlength="4" id="seccodeverify" onBlur="checkseccode()"></div><div class="notice" id="checkseccodeverify"> Refresh if you can't see it clear.</div>
<script type="text/javascript"> 
updateseccode(80, 35)
</script></td>
</tr>

But it can't stop the spams.

Re: Stop Spam

Sat, 31 Oct 2009 09:47:35 -0700

The best method to prevent spam is to use captchas before submitting anything. And if you want to take it a step further, throw up moderation.

Hello,

I am new for php.
I am helping our church to create a forum writeen with php. However the annoying thing is that everyday there are several new guys registering the forum and post spams.

How can I stop them?

I heard that we can add one authenticate statement when sign up.
Such as answer 1+1=2.

Is it true?
Can you please give me some sample codes?

Thanks
