加载时运行PHP脚本

Question

I have a PHP script which uses the value of an form input box to submit a twitter search via FileGetContents() , it returns the results on screen and stores them in a MySQL database.

Here is the form:

<form id="backup" action="backup.php" method="get">
    <div id="formContainer">
        <div class="rowtop">
            <span class="formw">
                <input class="search" type="text" onclick="this.value='';" name="tag" value="<?php echo urldecode($tag); ?>"/>
            </span>
        </div>
                <br>
        <div class="row">
                <br><br>
            <span class="formw">
                <input type="text"  onclick="this.value='';" name="maxpages" value="<?php echo $max_pages; ?>"/>
            </span>
        </div>
        <div class="rowbottom"><span class="label"><input type="submit" value="Backup" /></span></div>
    </div>
</form>

I'd like to have this script running as part of a CRON job, so instead of getting the search value from the input i'd like it to be the same value each time its run.

What is the easiest way to achieve this?

Answer 1

killer_PL's code would work... you're just setting the values manually at the start of the script.. an alternative would be to navigate to

"backup.php?tag=XXX&maxpages=XXX"

Answer 2

If I understood properly your question I would say you simply need the cron job to call directly the script:

backup.php?tag=value_you_set&maxpages=another_value_you_set

In the script you set the values for tag key and maxpages key. You sadi in your question they don't change.

Answer 3

Cron jobs are running in CLI environemnt, so you should familiarise yourself with this part of manual:

Answer 4

Set a few fake $_GET varaibles at begin of a script:

$_GET['tag'] = 'mytag';
$_GET['maxpages'] = 10;
$_GET['Submit'] = 'Backup';
